Product on quotation onlyDevis

The XDI-PID photo-ionization detector is a fixed VOC detector for measurement and detection of volatile organic compounds. It is a 4-20 mA linear output ATEX VOC transmitter with alarm relay and digital display (optional) which can be connected to a control system (PLC, gas detection unit) or used as an independent control point.

The XDI-PID Fixed VOC detector uses a PID lamp with 10.6 eV photo-ionization in diffusion mode which presents less contamination and maintenance problems than pump systems. This fixed VOC monitor offers the possibility of select 2 measuring ranges (0-50 ppm or 0- 1000 ppm) for better measurement accuracy. Detailed description

XDI-PID fixed VOC detector - Photo-ionization monitor

Volatile organic compounds (VOCs) include a multitude of substances characterized by their high volatility, that is to say that they emit vapors even in regular pressure conditions and at ambient temperatures. VOC exposure effects are very variable depending on the nature of the pollutant, ranging from olfactory discomfort to mutagenic and carcinogenic effects (benzene among others), passing through various irritations and decrease in respiratory capacity.

The XDI-PID is a photo-ionization detector for VOC monitoring using a 10.6 eV PID lamp. The device has a rugged and compact design to withstand harsh environments, it is ATEX and IECEx certified, which means it is suitable for most industrial applications.

The XDI-PID fixed VOC monitor photo-ionization detector is equipped as standard with 3 relays and a large LCD screen (optional) for easy reading of measurements. It uses a diffusion detection technique which leads to fewer contamination problems than sampling pump systems. Its maintenance is easy because changing the PID sensor takes only a few seconds.
