View our 7 PID sensors developed for the detection and monitoring of Volatile Organic Compounds in even the harshest of conditions.
Photoionisation Detectors (PID)
With a PID, the sample gas is exposed to deep ultraviolet light.
The emitted light ionises targeted gases and they are then detected by the PID electronics and reported as a concentration (ppb or ppm).
PIDs can measure Volatile Organic Compounds (VOCs) to very low concentrations. Considered the gold standard for VOC measurement, Alphasense PIDs are compact and low power, with recently improved electronics and longer lamp life. An extended family of lamps now include better BTEX and chlorinated VOC detection. These sensors are pin-replaceable with the 4P90 pellistor.
Alphasense PID Sensors
The Alphasense PID sensor range offers seven different models:
The sensors include a detector with lamp driver, amplifier circuitry, and user replaceable electrode stack, 10.6 eV lamp and particulate filter.
