Feature:1. 1. Gas Leak Detector: The gas leak detector with LCD display can detect the presence of many kinds of combustible gas and react very quickly. Compact and lightweight, easy to carry.2. 2. Ambient Humidity and Temperature: In addition to detect the combustible gas, the use of high-precision temperature and humidity sensors, used to measure the current environment relative humidity and temperature.3. 3. Audible and Visual Alarm: When the detector detects combustible gas, the number of analog strips will increase as the gas concentration increases; the buzz will increase as the gas concentration increases, and the backlight will change from green to orange and up to red as the signal increases.4. 4. Auto Power Off: When no operation within 10 minutes, no detection signal, the instrument will automatically shut down.5. 5. Sensitivity Selection: High / Mid / Low sensitivity are switchable for different scenarios.Specification:This product is a combustible gas leak detector, used for fast and reliable detection of combustible gas leakage on the gas pipeline.
