- MiniPID 2 PID sensor
A: The 10 eV MiniPID 2 has an extra window embedded within the electrode stack which allows 10 eV light through but not 10.6 eV light.
Q: Are there 3rd party results to support that Fence Electrode Technology is better than other technology available?
A: Yes, Ion Science has received independent verification from the state of Maine Department of Environmental Protection (ME DEP). Contact firstname.lastname@example.org to obtain the information.
A: Zero gas point: 30mV. 100ppm, Span: 100 to 250mV.
A: The MiniPID 2 includes a filter which allows for free diffusion of ambient air into and out of the sensor whilst preventing ingress of contaminants and particulates. The MiniPID 2 can also sample from a gas stream passed over the filter exterior. The flow should be a minimum of 100mbar.L/min, ideally 300 mbar.L/min and above.For more information please see the MiniPID 2 PID sensor manual.
A: It is possible for the MVI mercury vapour detector alarm to be adjusted below the specified safety alarm which is pre-set within the instrument, however, this should only be carried out by an authorised service technician. Please contact your local authorised service centre, who will be able to discuss with you an appropriate alarm level to suit your needs, and make the necessary arrangements for this to be completed.
A: No, PID sensors are non-selective and non-discrimatory. If a chemical can be ionised by the light then it will be sensed.
A: The GasCheck G2 is configured to display only one detectable gas and one unit of measure; these settings are chosen by the user during initial purchase. However, it is important to note that the GasCheck is not selective and cannot distinguish between detectable gases, therefore, GasCheck will respond to the presence of other detectable gases. For more information, please refer to our GasCheck G leak detector brochure.
A: Yes. Contact your local Authorised Service Centre and request a replacement certificate. Please note, a small fee applies for this request.
A: Yes, but you will need to ensure that the power you supply to the TVOC comes from an approved isolation barrier that is rated to your application.
A: No. The MiniPID 2 PID sensor is designed to fit Ion Science lamps. Using lamps from other sources could potentially damage the sensor and will void warranty.
A: The lamp life is based upon total hours illuminated, so powering off the sensor when measurements are not required will extend the lamp life.
A: No. Especially since dealing with mercury, the MVI mercury vapour detector should only be opened by an Ion Science Ltd Authorised Service Centre, trained to service the MVI. Any instrument opened by unauthorised persons will void the warranty, and may put users at risk. If you believe that there is an issue with your unit, please return it to your nearest MVI authorised Service Centre for inspection. If you can’t find one in your area you will need to return your instrument to the Ion Science head office. Please contact our Service department to arrange this; Email: email@example.com, Tel: 44 (0) 1763 208 503.
A: We would not recommend switching the orientation of the filter, as dirt/particles which had previously been captured by the filter may then be drawn into the instrument. Once the filter has been fitted, the orientation should remain the same.
A: PID will withstand pressure from near vacuum to several bar. Note that PID responses are normalised to the pressure (and temperature) at calibration and that instrument responses, given in parts per ppm, refer to the calibration temperature and pressure. For example, a ppm reading at near vacuum would relate to the same ppm reading, in air at 1 bar and 20°C.
Yes, for Tiger handheld VOC detector, Tiger Select handheld benzene detector, TigerLT handheld VOC monitor and Cub personal VOC detector. The instrument firmware can be upgraded via the PC software. Please refer to the instrument user manual for further details.
A: No. The unit will not charge whilst the unit is switched on; the MVI mercury vapour detector must be switched off when charging and the green LED light will illuminate to confirm charging is in progress. The instrument cannot be used to monitor an area whilst on charge.
A: The factory calibration data is written to an instrument during a factory calibration and can be used at any time. Factory calibration can only be overwritten by recalibration at an Authorised Service Centre.
A: Typical useful life for argon lamps (11.7 eV) is several hundred hours. Argon lamps include high UV transmitting windows made of lithium fluoride, which is susceptible to degradation by water vapour. Occasionally, lamp output is reduced by exposure to high molecular weight VOC’s, silicones or amines. However, lamps with lithium fluoride windows can be cleaned only by gently polishing the surface of the window with anhydrous ethanol or methanol on a cotton swab. Excess alcohol should be removed with a lint free tissue. Argon lamps not in use should be stored in an anhydrous environment to prevent slow degradation of the lithium fluoride window by ambient moisture.
A: The MiniPID 2 delivers more consistent lamp output on repeated power up and improved temperature stability. Otherwise MiniPID and MiniPID 2 are totally interchangeable as sensors. However, please note MiniPID 2 exclusively uses our recently developed long-life 10.6 eV lamps which are more powerful than the lamps that powered miniPID. Thus, if a long-life lamp is used in the original MiniPID the upper detection limit may be lower than specified. If a MiniPID lamp is used in MiniPID 2, then sensitivity may be lower than specified.For further information please see Technical Bulletin 168.
A: A clip tool is provided with the miniPID sensor which quick-releases the electrode stack and enables lamp inspection and cleaning, or lamp and stack replacement. The lamp, electrode stack and sensor body are easily reassembled, but refer to ensure this is undertaken correctly.
A: A searchable database is available on our website. If the chemical of interest cannot be found please contact us at firstname.lastname@example.org and advise the chemical name and CAS number ('CAS No.') to ensure it is correctly identified.
A: The fuse of the TVOC fixed PID detector can be replaced in a safe area for non-intrinsically safe application. If the application is for intrinsically safe use, the TVOC will need to be returned to the nearest service centre for replacement. The 125mA fuse will rupture due to over voltage or power surge. If this fuse is continuously blowing, please contact your local service centre for advice.
A: This is an indication that there may be a problem with the fan assembly. Please contact your local Authorised Service Centre for further information.
A: The presence of 'is' at the end of the instrument model number is an indication that a unit has Intrinsically Safe approval. Gascheck 3000is and 5000is instruments, which have black mouldings, are Intrinsically Safe. Instruments which have grey mouldings, such as the Gascheck 3000, 5000 and G models, are not Intrinsically Safe.Please do not hesitate to contact your local distributor for further information or advice.
A: We supply cleaning kits for lamps consisting of alumina powder and cotton swabs. Analytical grade methanol or ethanol can be applied to lamps to remove light contamination, and removed with a lint free cloth.
A: We would recommend using the Titan PC utility as this can be done from the comfort of your laptop. You can also use the in-built display to configure the unit. If you have any specific questions regarding setup, please contact your local Titan service centre or contact us through the usual service channels.
A: The ‘HPPM’ MiniPID2 sensor is able to detect whether the lamp is illuminated and will output a fault signal if it has not. There is also a hole at the base of the sensor through which the illumination can be seen.
A: This type of inspection and replacement of parts must only be carried out by a suitably qualified Titan service centre. Any unauthorised repairs and maintenance on your Titan will invalidate the instrument warranty.
A: Photoionisation detection or PID, works by exposing a test gas sample to high energy UV light. In a process called photoionisation, the light selectively breaks many volatile compounds, including most VOCs, into electrically charged particles or ions. The ions are attracted by an electric field to electrodes, where they pass through an electric circuit as a small electric current. This current is proportional to the concentration of the VOC. The MiniPID includes a third fence electrode (patented) to ensure that the amplified current does not include significant contributions due to other current sources such as water condensation on the PID enclosure walls.
A: The patented Fence Electrode PID manufactured by Ion Science eliminates the effect of water condensation on PID response. This ensures far more stable responses, and instrument clear down in very humid atmospheres.
A: The MiniPID fence electrode dose not interact directly with humidity. It provides an electrical barrier to the effects of low level humidity condensation in the PID enclosure with minimum interference to the PID output.
A: You need to arrange with your local service centre to have your instrument serviced every 6 months. There is a 'light-touch' service at 6 months and a more in-depth service every 12 months.
A: Ion Science recommends instruments should be serviced once every 12 months. Contact your local Authorised Service Centre for more information.
A: MiniPID 2, ex-factory, requires a supply voltage of 3.6V to 18V which then provides an internal rail voltage of 3.3V. As a result, the sensitivity of an unmodified miniPID is unchanged by supply voltage. The miniPID 2 contains a solderable pad on the underside of the sensor. If solder is applied across this pad, the sensor's internal regulator is shorted. The MiniPID 2 can then be supplied voltages of 3.0 to 3.6V and the PID will be provided an internal rail voltage just below the supply voltage. With the internal rail shorted, the miniPID lamp voltage varies with rail voltage. A higher supply voltage therefore increases the brightness of the lamp, and increases the PID sensitivity. A lamp will be approximately twice as bright running at 3.6V compared to running at 3.0V.
A: The TVOC fixed PID detector only displays ppm readings. To obtain a 4 to 20mA output, 5 to 28 V must be supplied to the coloured connectors in the instrument - please see the manual for details.
A: No, you must never alter or repair any components within the Falco. Certain components are critical to the instrument certification. Any changes will mean the instrument is unsuitable and unsafe for use within explosive environments.
Q: If the TVOC is being used in an application in which temperature changes rapidly with time, will this affect the PID performance?
A: Whilst the temperature itself should not be an issue, a change of more that 1°C per minute may result in heavy condensation on sensor surfaces.
A: The TVOC instrument house comprises a powder coated mild steel back, 304 stainless steel front plate. The sensor house is a nickel coated brass sensor cap.
This 'confidence beep' provides assurance that the instrument is operational where visibility is poor.
A: The following instruments are all Intrinsically Safe, please click on the links below to view the document for each instrument. You can also find further details on Intrinsic Safety in the specification for each instrument.
A: If PID is used without an appropriate filter, occasionally lint or small particles can get lodged between PID electrodes. In humid air, water may condense on these particles, enabling them to conduct electricity and deliver a false positive reading. If possible, remove and replace the PID electrode stack in the instrument. Particles may be removed by directing compressed air at the underside of the PID stack. Certain chemicals may produce deliquescent salts in the PID enclosure, which again in humid air, cause a substantial current between the electrodes. In this situation there is no alternative to replacing the electrode stack.
A: Ensure the test area is reasonably free of VOC's, for example by moving the instrument through several locations. The span gas portion of the custom calibration may be inaccurate. Set the instrument to factory calibration and see if the response continues to over-range. If it does, then ensure the ambient there are not some high levels of VOC present. Remove lamp and clean, blow out cell and re-calibrate. Contact your local Authorised Service Centre if this fails.
The pump error indicates that there may a blockage or leak within the system. Firstly, we would recommend checking to ensure that the inlet and outlet of the instrument are not blocked or restricted. Next, please check the PTFE filter at the probe inlet to see whether this requires replacement. Then, please inspect the sensor compartment, in which the mini PID sits, and inspect the blue sensor seal, electrode stack and lamp for signs of discolouration or residue. It may be necessary to carry out some simple user maintenance. Please refer to the Tiger user manual, and ensure that the instrument is reassembled securely.
If problems persist, please contact your local authorised service centre for further assistance.

A: Ion Science is part of an organisation called WEEE (Waste Electrical and Electronic Equipment). Being part of the WEEE directives, our WEEE Compliance Partner collects our disused instruments and takes them to a registered recycling centre. The instruments are then broken down/recycled/disposed of in an environmentally safe manner.To dispose of your old instrument safely, please return it to us and we will take care of it. Please note: there will be a cost to send your instrument back to our Ion Science UK Office. Please contact us for more information.
A: Our instrument software is thoroughly tested before being launched and is compatible with the most current Windows operating platform. For more information please contact us.
The Tiger handheld VOC detector should be charged for at least 7 hours before using it for the first time. To ensure optimum charging the Tiger should be switched off during charging. If left on, the Tiger will take longer to charge, but should not suffer any damage. The Tiger should be charged in a non-hazardous environment only.
The Cub personal VOC detector should be charged for at least 4 hours before using it for the first time. The Cub should be charged in a non-hazardous environment only.
It is important to ensure that the MVI mercury vapour detector is not left to charge for longer than 16 hours from a fully discharged battery. If the unit requires a top up charging then 2 – 8 hours charging should be sufficient. Please be aware that the MVI must be switched off to enable successful charging.
If you require any further information please contact your local authorised service centre.
A: The MVI mercury vapour detector requires a long charging period, however, we would recommend that the instrument is not left to charge for longer than 16 hours as this can damage the batteries and result in a shorter battery life. Charging your unit for 16 hours should result in a running time of approximately 6 – 8 hours. It is also important to ensure that the instrument is charged using the charger provided.
A: A 10.6eV PID lamp has a life expectancy of 10000 hours continuous use. An 11.7eV lamp has a life of approximately 200 hours.The life expectancy of the 11.7eV lamps is affected by the sensing environment as they cannot be polished when contaminated.
A: Although we do not permit users to open the MVI units, there are some external checks and maintenance that may be carried out. We would advise that users always run the unit using the external filters provided; this reduces the chance of contaminants being drawn into the unit and causing internal damage to components.Filters should be replaced on a regular basis; depending on application and environmental conditions, this could be once every week to once every 3 months. When the filter is showing signs of contamination replace immediately. For further details, please refer to the MVI mercury vapour detector manual.
A: The maximum flow that can be presented across the TVOC is 300mL/min. Higher flows are likely to cause signal instability.
A: The MiniPID 2 PID HPPM2 sensor uses the photoionisation current to determine whether the lamp is illuminated. If the lamp is not illuminated, the ionisation current will be zero, and the signal output switches to 35 mV, indicating failed state. The lamp out error will also be raised if the lamp light is very weak and the atmosphere very free of VOC’s.
A: If the MiniPID 2 PID sensor is reading high in a humid environment then it likely that the electrode stack has become heavily contaminated and the electrode stack should be changed.
A: Over a lifetime of usage the lamp power will decay, and therefore the sensitivity of the sensor will do too. This can be up to 5% per month, and should be taken into account when considering calibration periods.
A: The lamp will take a maximum of 15 seconds to illuminate, and sensor to stabilise. After periods of storage or non-usage the MiniPID 2 PID sensor may be susceptible to baseline settlement whilst semi-volatiles which have accumulated in the PID voer time are driven off. To remove this background the MiniPID 2 sensor should be powered in a clean air environment for an hour or two.
A: Please refer to the diagnostic section of the manual. The manual can be downloaded from the Ion Science website.
A: Recalibrate the instrument and monitor readings. We would recommend that you recalibrate on at least a monthly basis (depending on your site risk assessments).
A: Care must be taken to avoid touching the PID lamp window with the hand as this can result in a film on the lamp which prevents UV light transmission despite looking perfectly clean. Powder-free gloves should normally be used when handling lamps.
Q: I noticed my lamp has a chip on it. It still lights up and the instrument reads gas okay. Do I need to get a new lamp?
A: Any chip on the lamp window will decrease the sensor response to gas. It also may cause gas leakage paths which prevent rapid sensor response and clear down. Replace lamps which show any visible defects.
A: The coarse particle filter should be typically replaced after every 40 to 400 hours use depending on the operating environment. the filter may need replacing more often in environments prone to high particulate levels, including mists and condensates of all kinds. When the filter is showing visible signs of contamination replace immediately.
A: Normally we suggest to perform a bump test in normal measure mode with a CalCheck SF6 attached to the probe. If the bump test is not within the tolerance level (approx. +/- 5 .. 10 %) than we suggest to perform a calibration.The frequency of bump test is in relation to the user profile of the instrument. For example, if the instrument is being used as a service instrument for field use, it should be tested before it is sent out. On the other hand a production instrument should be tested either every morning or every week.The calibration of the instrument is quite stable and we believe the clients will find out rather quickly if they need to perform a test every morning or every week.
A: Please be aware that the IP rating of the TVOC enclosure is IP65 and of the sensor housing is IP54. The TVOC can be mounted in areas subject to rainfall. The TVOC can be mounted in areas subject to rainfall. However, the sensor housing should be mounted at least 300mm (12in.) clear of any horizontal surface subject to rain.
A: During continuous operation the MiniPID 2 PID sensor consumes approximately 110 mW. Please note that on power up the sensor demands 130mA (430(mW) for ~0.1 s.
A: Ion Science is affiliated to WEEE (Waste Electrical and Electronic Equipment). In meeting WEEE directives, our WEEE Compliance Partner collects our disused instruments and takes them to a registered recycling centre. The instruments are then broken down, recycled or disposed of appropriately. To dispose of your old instrument safely, it may be returned to our UK office for recycling. Please note: there will be a cost to send your instrument back to our Ion Science UK Office. Please contact us for more information.
It is not uncommon for the displayed reading to drift slightly. Ensuring that you are in a clean environment or using a carbon filter, adjust the central Zero Adjust Button to set the display to 0μg/m3, or 0.0μg/m3 on the 200μg/m3 range. If you feel that the displayed response is changing rapidly, please contact your nearest Authorised Service Centre.
A: A development board for MinPID 2 PID sensor evaluation is in progress and will be released 2018.
A: Most volatile organic carbon compounds are detected by PID. The 11.7 eV (argon lamp) powered PID detects all compounds except for methane, ethane, and most fluorocarbon. 10.6 eV (krypton) PID additionally does not detect some other C1 and C2 compounds such as methanol and acetylene, and many nitriles and chlorocarbons.
A: A response factor is a dimensionless number indicating the relative PID response to a particular VOC versus the response to isobutylene. If a PID is calibrated to isobutylene, and the identify of a target VOC in air is know, then a response factor can be used to convert the PID signal into a measurement of its concentration. Response factors values can be either inferred from the chemical structure or tested directly. Response factors are different for different photon energy outputs used in PID, i.e 10.0 eV, 10.6 eV and 11.7 eV.
A: An AirSepFilter is a special type of filter, designed by ION Science to separate Benzene from air. This is how the Titan measures the Benzene content within the sampled air.
A: Both Pumped and Diffused Falco models are rated to IP65. Please make sure this is suited to your application before installing the Falco.
A: Firmware versions are displayed on your instrument during start-up.
A: This can be identified from the instrument display during power-up.
A: The Falco has an operational range of 8-40 Volts DC. We would recommend that you provide a power supply of 24 Volts DC. The maximum power consumption at 24 Volts is 6.7 watts.
A: Any fixed gas detector needs to be installed in a location so that it can detect gas accumulation before it poses a serious hazard to personnel and equipment. The factors you need to consider are:-
- The process plant and equipment
- Any ATEX zoning on your site.
- The number of instruments installed in an area. Is the quantity sufficient to protect workforce or process?
- The properties and dispersion behaviour of the measured gas.
- The available ventilation.
- Other safety issues include location of personnel or equipment protection.
A: An ION Science Titan is a precision instrument, specifically designed for detecting Benzene. The typical deployment for a Titan is within extremely harsh conditions and, as such, the instrument must be serviced regularly to ensure the safe continued operation of the instrument.
A: The likely causes are contamination of the lamp window and the degradation of lamp output. If the lamp window is cleaned and the output signal is still low then the lamp and/or stack needs to be replaced. If there are spare lamps and electrode stacks to hand then a simple test will confer which component is faulty.
