In general, online fixed formaldehyde gas detectors are connected by a separate line system between the main controller and the detectors. The detectors are distributed at multiple monitoring points, and the main controller centrally controls them. The gas concentration of each detector is displayed independently. When the gas concentration of the detector in the environment reaches or exceeds the preset alarm value, the main controller will issue an alarm to remind the on duty personnel to take safety measures and ensure the safe production of the enterprise.
