GA10 portable combustible gas detector (hereinafter referred to as detectors), is a work environment can be continuously measured the concentration of toxic and harmful gases intrinsically safe apparatus. It applies to toxic gas leak disaster, underground pipelines or in mines and other places, can effectively guarantee the safety of staff from abuse, from loss of production equipment. Detector for the detection of gas concentrations in the natural diffusion, using imported electrochemical sensors with excellent sensitivity and excellent repeatability; equipment using embedded micro-control technology, the Chinese menu is simple, functional, high reliability and performance of the whole home leading domestic level. Detector housing projects with high strength materials, composite elastic rubber material crafted, high strength, feel good, and waterproof, dustproof, explosion-proof. This product is suitable for detection of combustible gases in ambient air concentrations, widely used in metallurgy, power plant, chemical industry, mines, tunnels, trenches, underground pipelines and other places, effectively prevent poisoning accidents. Features: import sensor, stable and reliable; automatic calibration and zero; large screen LCD: Chinese operation interface; battery power display, voltage prompt, low-voltage automatic shutdown; with real-time clock function; two triple alarm (sound, light, vibration), difficult to ignore; boot full function self-test, sensors, batteries, circuit and alarm functions; 2000 set of data storage; sensor fault detection and alarm; password management, password authentication key operation required to effectively prevent misuse automatic calibration function and reduce the measurement error;
