The world’s largest PID sensor manufacturer. Available through Gastech.

Benzene at 0.02 parts per million. VOCs at 1 part per billion. ION Science built the instruments that make those numbers possible.
There is a reason ION Science is trusted by gas detection manufacturers worldwide to supply the sensor at the heart of their instruments. Their photoionisation detection technology is independently verified as the best performing on the market for speed, accuracy, resistance to humidity and contamination. When accuracy is measured in parts per billion, the sensor is everything and nobody makes a better one.
ION Science is the world’s largest PID manufacturer, supplying more PID sensors than any other gas detection company in the world. The ION Science PID sensor is found within most PID instrumentation available today for the detection of volatile organic compounds. But beyond the sensor, ION Science builds instruments that are genuinely best in class.
The Tiger XT is the most advanced handheld VOC detector on the market with the widest measurement range, accurately detecting gases down to 1 part per billion up to 20,000 parts per million, with the fastest response time on the market of just two seconds. Its patented Fence Electrode Technology and anti-contamination design ensures optimal performance in humid and heavily contaminated atmospheres the kind of real-world conditions that defeat lesser instruments. For benzene-specific detection, the Tiger XT Select delivers portable benzene monitoring down to parts-per-billion levels, with the ability to switch seamlessly between benzene-specific mode and standard VOC detection in the field.
At the personal monitoring level, the Cub is the world’s smallest and lightest personal VOC monitor, delivering market-leading parts-per-billion sensitivity in a form factor small enough to clip to a lapel. For workers in petrochemical, pharmaceutical, environmental and industrial environments where VOC exposure is a daily reality, the Cub provides early warning before exposure levels become a health concern.
For fixed benzene monitoring, the Titan 2 is the only commercially available truly selective fixed continuous benzene monitor worldwide, detecting benzene at levels as low as 0.02 parts per million well ahead of tightening global benzene exposure limits. As regulatory requirements for benzene monitoring become increasingly stringent across Australia and internationally, the Titan 2 gives operators the confidence that their monitoring program will remain compliant regardless of where the limits go.
