PID sensors are the ideal choice for detecting low concentrations of volatile organic compounds. A PID (photoionization detector) is used to measure hazardous substance groups or can even be adjusted to measure individual substances.

Detection of volatile organic compounds in the ppm and ppb range

The photoionisation detector (PID) sensors complete the DragerSensor series in the area of detecting volatile organic compounds (VOCs) in the ppm or ppb ranges. Therefore, these sensors are a useful addition to workplace monitoring with multi-gas detectors in certain applications.

Many different applications

PID sensor technology is very versatile and can be used, for example, for clearance measurements during shutdowns in the chemical and petrochemical industries, monitoring operations in shafts and enclosed spaces, detecting leaks and many other applications.

Benzene-specific measurements

Selective benzene detection can be carried out using the Drager X-am 8000 in combination with the benzene pre-tube. This pre-tube filters out all hydrocarbons present except for benzene.

Robust design

The Drager PID detectors are equipped with water-repellent membranes to protect the integrated PID sensor during industrial use. The sensors also have very short response times and give a rapid warning.

Adjustment and response factors

PID sensors are quickly and simply adjusted using isobutylene. Isobutylene is a harmless gas that is available in practical, disposable, test gas bottles. Sensitivity to the monitored substance can then be individually set using response factors. This means that it can be calibrated on location at any time.

Optimised for the mission

?Optimised for compatibility with original Drager gas detection devices, so the PID sensors can be used to their full potential.
