Detects multiple gases: household gas detector suitable for detecting LPG (methane), natural gas, charcoal, gas gas, artificial gas, liquefied petroleum gas, liquefied natural gas, etc. . Digital LED display and audible warning: The gas detector offers voice notification and digital reading of gas concentration. When the gas leak concentration reaches the preset level, the alarm provides a visual and audible signal. 85dB loud alarm, reduce the risk of gas explosion and protect your family's life and property. Easy to install: The gas leak detector adopts an easy-to-install design, can be used by plugging it directly into the power socket to detect gas leaks. Widely used: This product can be used as an independent family alarm equipment, and can also be used as a detector front alarm system. Widely used for restaurants, hospitals, hotels, oil factories, garages, gas stations, etc. Precautions: The system preheating time is about 2-3 minutes. During this period the gas test will not work. You must wait until the display shows 0 (the system enters working state) before it can be tested normally. The gas leak detector adopts easy to install design, can be used by plugging it directly into the power socket to detect gas leaks. Detection gas: liquefied gas, natural gas, gas artificial Supply voltage: AC100V~AC240V Power frequency: 50/60 Hz Rated power: less than 2 W Gas detected: natural gas, LPG, coal gas Alarm concentration: 3% LEL ~ 20% LEL Alarm sound level: greater than or equal to 85 dB (at 3 meters from the product) Operating temperature: -10~40 Operating temperature: less than 97% RH It is an independent combustible gas alarm, adopts advanced gas detection technology international and selects economical microprocessor as the control core.It is a small gas safety protection product suitable for use in the family.Leakage concentration, when the leakage concentration reaches the set value, the detector will emit a audible and visual alarm. When the gas concentration inside is lower than the alarm setting value, the detector will automatically return to the normal working state, which can avoid the occurrence of personal losses and property accidents such as Poisoning, explosion and fire caused by the leakage of combustible gas. . Features 1. Using high quality semiconductor heating sensor, good stability. 2. MCU intelligent control monitoring, SMT placement process 3. With on-site sound and light alarm function. 4. The tube's digital display technology indicates the instantaneous air leak concentration. 5. Three indications: power indicationPOWER, status indicationSTATE and alarm indicationALARM. Technical indicators Detection gas: liquefied gas, natural gas, gas artificial Operating voltage: AC100V~AC240V 50/60Hz Rated power: less than 4W Alarm concentration: Liquefaction: 0.1~ 0.5% Natural gas: 0.1~ 0.3% Gas 0.1~ 0.5% Alarm volume: 85dB (3 meters from the product) Operating environment: -1050, relative humidity
