Gas Alarm Detectors- LPG/Natural/Coal Gas Combustible Gas Detector for Home, Propane Butane Methane Gas Sensor Strobe Light Warning, Digital Display Plug-in Gas Leakage Detector (White)

The use of gas leak alarms is one of the important ways to protect the safety of families and others. When the concentration of flammable gas exceeds the alarm set value, our detector will be triggered to alarm, and an audible and visual alarm signal will be given. It is necessary to take safety in time. Measures to avoid explosions. Warming Tip: It takes about three minutes to enter the warm-up state after power on. Please do not do anything during this time. When the warm-up is completed, it will automatically enter the working state. Working status: Gas detectors monitor and display the gas concentration (0~9) and "A" on the screen in real time. 1. When the screen displays 1-2, it will not alarm, don't worry, this value will not cause harm to the human body. 2.More than 3 LEL at a time, and immediately triggers 85db low-frequency sound "di...di...di ....." alarm and flashing light at 3-5LEL. 3.Immediately after 6-9LEL Trigger the 85db high-frequency sound "dididi...dididi..." alarm and flashing light. 4.If the gas concentration exceeds 9LEL, it will immediately trigger the 85db fast-frequency sound "Whistle alarm" and flashing lights.The screen displays the letter "A" Specification: Power supply: AC100 V ~ AC240 V Detection concentration: LPG: 0.1 - 0.5%; natural gas: 0.1 - 0.3%; Coal Gas 0.1 - 0.5% 85 dB loud alarm sound Visual Warning: Green: System is on, electric connected. Yellow: Fault, sensor has lost efficacy. Red: Gas leaks, and the sirens alarm. Height: 121 mm Width: 69 mm Weight: 140 g Maintenance points of the gas detector: 1. Avoid placement in close proximity to where airborne contaminants like cooking oils can coat and decrease sensor sensitivity. 2. Users may clean exterior surface of the detector, unplug the device before cleaning.
