Compur Monitors GmbH & Co. KG products

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.
