DART SENSORS Operation manual for WZ-S-K HCHO Module
2
Brief Introduction
WZ-S-K 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-K HCHO module is pre-calibrated in
the factory and can be integrated into your system directly.
