Fixed gas detectorsFixed Gas Detectors

PIDScan 800 is a revolutionary state-of-the-art fixed gas detectors based on PID technology for continuous measurement of VOCs.  It is the world's first fixed type, ex-approved VOC detector with automatic self-cleaning feature.  Literally, there is no cleaning of the lamp required.  Both zeroing and span calibration can be carried out automatically.   The transmitter has resounding performance even in high temperature and humidity conditions; as a result of its unique “Earth-ring guard” technology, and built-in temperature and humidity sensors for real-time compensation.
