PIDX-A-004 Volatile Organic Compound Sensor

VOC Gas Sensor, Photoionisation Detector, A-Series, 0–4 ppm ultra-low range

Ultra-low-range PIDX sensor for ppb-level VOC detection in IAQ and cleanroom applications

The PIDX-A-004 is an advanced PIDX photoionisation detector (PID) for VOC measurement from 0 to 4 ppm with a 10.6 eV UV lamp and a minimum detection level down to approximately 0.5 ppb. It is engineered for indoor air quality, cleanroom and low-level environmental VOC monitoring where small changes in concentration must be measured reliably. The enhanced PIDX architecture provides stable baselines, excellent sensor-to-sensor repeatability and low power consumption for both portable and fixed instruments.
