Threshold Formaldehyde HCHO Detection Sensor (0-20ppm)

Threshold Formaldehyde HCHO Detection Sensor (0-20ppm)Threshold Formaldehyde HCHO Sensor offers an easy to use solution to monitor HCHO levels. This device features a wide voltage range (5 24V) & has both high & low level signals. Plus, it has an indicator light to quickly check the status. If the gas concentration exceeds the set threshold, the device will output a high level signal & the light will be on. When the gas concentration falls beneath the threshold, the sensor emits a low level signal & the

3V connections since those are so useful
