Condition: 100% Brand New Item Type: Gas Alarm Sensor Material: ABS, Electronic Components Working Voltage: 90-240V Alarm Current: 100mA Quiescent Current: 0.5uA Detection Angle: 120 Degrees Detection Distance: 20m / 65.6ft Working Environment: Temperature: -10-50 ℃ Relative Temperature: <95% Alarm Volume:> 70dB Sensor Life:> 5 Years (In Clean Air) Alarm Concentration: Gas: 0.1-0.3% Natural Gas: 0.1-0.5% Liquefied Petroleum Gas: 0.1-0.3% Application: Gas, natural gas, liquefied petroleum gas leakage alarm Weight: Approx. 176g / 6.2oz Product Size: Approx. 7x4x11.5cm / 2.8x1.6x4.5in Alert Handling: When the concentration value of combustible gas in the ambient air reaches or exceeds the alarm setting concentration value, the detector will automatically enter a continuous alarm state, then: 1. Close the pipeline valve immediately. 2. Open the window immediately to circulate the indoor air. Avoid using all items that can generate sparks (such as lighters, matches, etc.). 4. Avoid switching on and off electrical appliances. 5. Check the cause of gas leakage, and promptly notify relevant departments and relevant professionals to deal with it. After inspection, if the detector is a false alarm, the user should check whether the installation position of the detector is appropriate. 1、The detector uses the most advanced semiconductor gas sensor, safe and reliable, and has a long service life. 2、Built-in high reliability sensor, high sensitivity, can sense gas, natural gas, liquefied gas. 3、The gas alarm can be used to detect gas, when the gas concentration exceeds a certain level, it will immediately send an alarm signal. 4、Made with high-quality ABS and electronic components, has good durability and stability. 5、Support automatic fault detection and display, automatic reset, suitable for home use. 1 x Gas Alarm Sensor 1 x Screw 1 x Nut 1 x Wall-Hanging Plate
