- detection of volatile organic compounds in low concentrations
- compatible with: X-am 7000 and X-am 8000 – selective benzene measurement with pre-tubes possible
- measuring range: in ppm and ppb range
The photoionisation detector (PID) sensors complete the DrägerSensor 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.
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.
Selective benzene detection can be carried out using the Dräger X-am® 8000 in combination with the benzene pre-tube. This pre-tube filters out all hydrocarbons present except for benzene.
The Dräger 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.
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 compatibility with original Dräger gas detection devices, so the PID sensors can be used to their full potential.

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.

Matter with a temperature above its boiling point is said to be a gas. With respect to a human environment (normal conditions), any substance with a boiling point below 20°C at normal pressure is a gas.
