When toxic gas is present in the detected area, the detector converts the gas signal into a voltage or current signal and transmits it to the alarm device. The instrument displays the gas concentration as a percentage of the Lower Explosive Limit (LEL) of the toxic gas. When the toxic gas concentration exceeds the preset alarm threshold, an audible and visual alarm will be triggered to prompt on-duty personnel to take timely safety measures, thereby preventing combustion and explosion accidents.
