DART SENSORS Operation manual for WZ-S HCHO Module Dart Sensors WZ-S formaldehyde module Operation Manual

DART SENSORS Operation manual for WZ-S HCHO Module Brief Introduction WZ-S formaldehyde module from global detection expert DART SENSORS combines novel HCHO sensor with advanced electronic control technology, converting HCHO concentration into PPM directly. Once HCHO arrives at working electrode (anode) it is oxidized instantaneously to generate an electrical signal. The electrical signal is then acquired and processed by microprocessor into a PPM value and is output by standard digital signal. WZ-S HCHO module is pre-calibrated in the factory and can be integrated into your system directly....
