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.
