Gasdetector Statox 501 PID: Detects VOC Gases and Vapors

Statox 501 PID – the Allrounder

PIDs (Photo – Ionisation – Detectors) detect VOCs (Volatile Organic Compounds) in the ppm range, which other sensor types are unable to monitor, like solvents and fuels.

A PID sensor uses high energy ultra violet light radiation to break gas molecules into radicals, which are discharged while passing a condenser. The discharge current increases proportional to the number of molecules, i. e. the gas concentration. The standard Statox 501 PID will detect all substances with a ionization energy below 10,6 eV

PIDs are normally calibrated with Isobutene. Other gases will be detected with different sensitivity. These so – called response factors must be multiplied with the displayed concentration when adjusting span. Compur Monitors will adjust your Statox 501 PID individually to your application ex works.

A magnetic pin gives access to simple parameter setting and calibration menu. A multi – color LED signalises the status of the system.

The Statox 501 PID voltage output signal is similar the the signal of a catalytic sensor. The Statox 503 control module displays the measured value and provides an analog output and 3 powerful relay outputs for alarm devices or pcs.

Caution! The PID must be connected to different Terminals on the Statox 503 and the Statox 502 control modules. Please follow the connection intructions!
