VOCScan800 is newly developed PID type VOC detector. It has built-in self-cleaning and self-zeroing functions and can be used to detect a wide range of volatile organic gases (VOCs).
VOCScan800 Fixed VOC Detector
Description
Features
Automatic / manual zero calibration, manual zero calibration on site
Equipped with many selectable functions
Multiple detection ranges (0.0-100.0ppm, 0-1000ppm and 0.00-20.00ppm)
Default factory detection range is 0.0-100.0ppm
Built-in intelligent processor can manage multi-port valves and regulate the flow of clean air to the detection air chamber
With self-cleaning function, the detector can wash away the pollutants in the sensor through the circulation of clean air, which ensures the measurement accuracy of the sensor, thereby reducing the workload of on-site maintenance.
End user can set the time of self-calibration and self-cleaning cycle
Cleaning Interval / Self-Zero is 60 minutes
Application
This product is suitable for a variety of scenarios, such as petrochemical refining, synthetic fiber manufacturing, gas leakage collection and environmental protection information detection.
