Oil and Gas

Gas detectors and Leak detectors for the Oil and Gas industry for the workforce, workplace safety, and the environment.

The oil and gas industry poses many potential risks to the workforce, workplace, and the environment. Hazardous gas emissions are prevalent during production and processing operations with exposure to benzene being a significant concern.

Benzene is commonly found throughout the industry as a constituent of crude oil however, it is extremely hazardous and a known carcinogen. Legislation has been put in place to ensure worker exposure is kept to a minimum.

With over 30 years of knowledge and expertise within the oil and gas industry, we understand the need for fast, accurate, reliable gas sensors, and instrumentation. In fact, we are the only company in the world to offer a complete portfolio of personal, handheld, and fixed benzene detectors.

Our range of oil and gas PID solutions are designed specifically to meet customer requirements and offer the very best detection capabilities available. All of our PID technology incorporates patented Fence Electrode Technology, with the ultimate resistance to humidity and contamination for reliable performance within the harshest working environments, minimizing drift issues and maximizing the uptime of your instrument saving both time and cost to your business.

Oil & Gas Applications

Fence Line Monitoring


ION Science can help refineries to monitor the fence line of their facilities for concentrations of benzene and other volatile organic compounds (VOCs). Continuous area monitoring for airborne toxic or noxious gases can protect worker and site safety inside a perimeter.

According to EPA (Method 325), the regulatory objective of refinery fenceline monitoring is to manage benzene and eventually other toxic VOCs. The primary risk factor is the supply of breathable air and the dangers presented by toxic gases.

Confined Space Entry


When your workers enter confined spaces, you want the confidence that comes with ION Science gas detection equipment, that your operatives are protected.

ION Science instruments detect common toxic gases and use their own MiniPID gas sensor to signal the presence of VOCs to keep workers safe during entry or rescue operations.

ION Science solutions help you meet regulatory requirements.



Spills of crude or refined petroleum products will always require prompt and professional attention with a response appropriate to the scale of the spill and the material to be controlled.

First responders will require personal protective equipment (PPE), which might be as simple as footwear, gloves, and eye protection, or as comprehensive as a full Hazmat (hazardous materials) suit with breathing apparatus.

Determination of the level of protective clothing required for a specific incident will follow an assessment of the specific petrochemical products to be dealt with. Portable gas detectors are an important part of this assessment.

Specific hazards are presented by spills due to the uncontrolled release of toxic and carcinogenic aromatic hydrocarbons including benzene, toluene, and xylene. Further hazards may be presented by chemical dispersants, which may release noxious compounds including hydrogen sulfide (H2S), which is recognized by its ‘rotten egg’ smell and is very poisonous.

For the rapid determination of volatile organic and total aromatic compounds the Tiger range of VOC detectors is the ideal choice. Utilizing patented photoionization detection (PID) technology, the instruments are immune from the effects of humidity, giving them a distinct advantage in spill situations. The Tiger range of instruments measures TVOCs rapidly and accurately, providing essential information in spill management.


For personal protection, workers may be fitted with a Cub wearable VOC detector to provide assurance that individual exposure remains within limits, or enable appropriate aftercare if limits are exceeded.



Protect your workers and your surrounding communities against high concentrations of toxic gases and VOCs with the flexibility of ION Science gas detection equipment.

ION Science monitors are proven, intrinsically safe, and can be used in harsh operating environments anywhere around the rig. ION Science gas detectors can also provide you with continuous monitoring to improve safety and streamline compliance.



Fracking is the process of drilling into the ground to release gas from inside rocks. Pressurized fluids are used to create fractures.

Although fracking is arguably emitting less carbon dioxide than coal, it still has its effects on the environment.

Gas detection instruments are used to prevent lost time injury, illness, and occupational fatality.

Plant Shutdown and Turn-around


Shutdown and maintenance are important periods in the yearly cycle at many facilities. Anything delaying the programmed activities can be a cause of significant cost as well as inconvenience, whilst also always ensuring optimal safety during plant and refinery turnarounds.

ION Science’s range of fixed and portable gas detectors can help you maximize turnaround efficiency, reduce downtime, and get back to production quickly.
