Fixed VOC Detector

... extended warranty  with long sensor life

Model PIDScan 800

PIDScan 800 is a revolutionary state-of-the-art fixed  VOC 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.




Automatic self-cleaning

to ensure reliable, improved life and operation performance of the PID lamp


for fast repeatable response and  

accuracy for long duration 

Unique ceramic-glass PID sensor 

has proven to yield stable performance and long-sensor life beyond expectations

Built-in temperature and humidity sensors

to ensure accurate and real-time compensation measurements under all weather conditions

  • 4-20 mA analog and MODBUS RS485 output ; HART as optional.

  • PID sensor highly resistance to humidity interference

  • Explosion proof EEx d IIC T6 for hazardous application

  • With built-in diaphragm pump to draw in sample gas

  • Magnetic interface for non-intrusive access to menu

  • Large numerical and graphical dot-matrix display with backlight sensor
