MiniPID 2 HS PID sensor

0-3 ppm range, 0.5 ppb sensitivity, 10.6 eV lamp

Designed for OEMs, the MiniPID 2 HS high sensitivity PID sensor is the latest in the range of PID sensors from Ion Science for sub-ppb level detection. 

The ground-breaking MiniPID 2 HS is 15 times more sensitive than the existing MiniPID 2 ppb sensor. It is capable of detecting trace levels of volatile organic compounds (VOCs) over a long period of time making it ideal for indoor air quality monitoring applications. It is also well suited to clean rooms, fence line monitoring, industrial hygiene, site soil and air sampling, fugitive emissions, volatile spills, law enforcement and emergency response.

Delivering a dependable response to thousands of VOCs across many diverse applications, the MiniPID 2 HS is a simple plug and play sensor providing a wide detection range of 0.5 ppb up to 3 parts per million (ppm). Ion Science’s MiniPID 2 HS also features a re-designed, pneumatically sealed electrode stack for high sensitivity and a wide detection range.

An innovative self-diagnostic feature indicates whether the electrode stack is contaminated or if the sensor is not operating correctly. The MiniPID 2 HS incorporates Ion Science’s long-life lamp that offers 10,000 hours continuous operation. Together with exceptional brightness and improved stability, this facilitates reliable detection of less volatile and less readily sensed compounds, over an extended period of time.

Like Ion Science’s other market-leading sensors, MiniPID 2 HS incorporates patented Fence Electrode Technology which is proven to resist humidity and contamination for optimum detection of VOCs in challenging environments.

Amongst the benefits offered by Ion Science’s MiniPID 2 HS sensor are its low running current, robust lamp illumination, reliable operation at extreme temperatures and ease of serviceability.

The MiniPID 2 HS is designed for both diffusive and in-line pumped sampling, delivering an exceptional response time and clear down. It boasts intrinsically safe certification and is ATEX, IECEx, II 1G Ex ia IIC T4 Ga accredited.

Ion Science manufactures and supply more photoionisation detection (PID) sensors than any other company in the world with our sensor technology trusted by major gas detection manufacturers, globally.
