(Carbon monoxide alarm) is my company developed a new generation of high-tech electronic products, gas alarm (carbon monoxide alarms) using high-precision sensor as the detection element, high sensitivity, fast response. When the concentration of gas alarms detect gas into the environment (carbon monoxide) reaches or exceeds the preset alarm value, gas alarms (CO alarm) immediately audible alarm to alert us take safety measures to prevent poisoning, explosion and fire, in order to protect life, safety and property. Gas alarm (carbon monoxide alarms) is widely used in petroleum, chemical, metallurgy, municipal and mining industries. Features: Imported components, stable performance Interference, sensitive and reliable environment using a wide range of long life Specifications: Operating voltage: DC12V Detection of gas: gas, carbon monoxide, hydrogen, acetylene, natural gas, liquefied petroleum gas, hydrogen sulfide, chlorine, sulfur dioxide and other detection principle: Choi combustion, electrochemical detection range: 0-100% LEL, 0-100ppm, 0-1000ppm response time: ≤30s Recovery time: ≤60s Power: ≤3.5W / Road Measurement error ≤ ± 5 % LEL proof grade: ExdⅡBT6 Operating temperature: -20 ℃ --70 ℃ Humidity: ≤90% RH
