The online combustible gas concentration detector (for LEL measurement) can accurately and in real time detect the gas concentration and leakage conditions in various environments. It adopts imported sensors and microcontroller technology, featuring fast response, high precision and good stability. Its explosion-proof design is suitable for various hazardous locations. This device is compatible with alarm systems, PLCS, DCS and other control systems, and can achieve on-site alarm, 4-20mA standard signal and relay switch output. It is mainly applied in places such as petrochemicals, coal mines, metallurgy, municipal works and laboratories where there is a risk of flammable gas leakage and explosion.
