Brief introduction of G80290 portable gas detector product: The G80290 portable gas detector (hereinafter referred to as the detector), is a kind of continuous detection of intrinsically safe equipment operation environment of toxic, flammable and explosive gas concentrations. It is suitable for the explosion, leakage of poisonous gas, mine rescue underground pipeline or other places, can effectively ensure the life safety of the staff are not infringed, production equipment from loss. Tester for natural gas diffusion concentration detection, using imported electrochemical sensor (gas for catalytic combustion type), with excellent sensitivity and good repeatability; instrument using micro control technology embedded Chinese menu, simple operation, complete function, high reliability, the performance of the leading domestic level. Housing detection instrument with high strength engineering material, composite material and refined, high strength, good hand feeling, and waterproof, dust-proof, anti explosion. This product is suitable for detecting ammonia concentration in air, widely used in metallurgy, power plant, chemical industry, mine, tunnel, tunnel, underground pipelines and other places, effectively prevent poisoning accident. Characteristics of G80290 portable ammonia detector: ◆ import sensor, stable and reliable performance Automatic calibration and zeroing The large screen liquid crystal display Chinese interface The battery power display in real time, undervoltage tip, low voltage automatic shutdown ◆ with real-time clock function ◆ two grade three alarm (sound, light, vibration), not easy to ignore ◆ boot full functional self testing, sensor, battery, circuit and alarm function The 1000 groups of data storage The sensor fault detection and alarm ◆ password management functions, important operations require password authentication, effectively prevent the misoperation Automatic calibration function, reduce the measurement error Product name The measured gas Measuring range Optional range Resolution Response time Carbon monoxide detector / alarm CO 0-1000PPm 0-500/2000/5000PPm 1PPm ≤ 20 seconds Oxygen detector / alarm O2 0-25%VOL 30%VOL 0.1%vol ≤ 20 seconds Ozone detector / alarm O3 0-10PPm 0-100PPm 0.01PPm ≤ 20 seconds Hydrogen sulfide detector / alarm H2S 0-100PPm 0-50, 200, 1000PPm 1PPm ≤ 30 seconds Hydrogen detector / alarm H2 0-1000PPm 0-5000PPm 1PPm ≤ 30 seconds Chlorine detector / alarm CL2 0-20PPm 0-10, 100PPm 0.1PPm ≤ 30 seconds Ammonia detector / alarm NH3 0-100PPm 0-50, 500, 1000PPm 1PPm ≤ 30 seconds Sulfur dioxide detector / alarm SO2 0-20PPm 0-50, 1000PPm 0.1PPm ≤ 30 seconds Nitric oxide detector / alarm NO 0-250PPm 0-500PPm 0.1PPm ≤ 30 seconds Nitrogen dioxide detector / alarm NO2 0-20PPm 0-50, 100PPm 0.1PPm ≤ 30 seconds Formaldehyde detector / alarm CH2O 0-50PPm 0-5, 10PPm 0.01PPm ≤ 30 seconds Hydrogen chloride detector / alarm HCL 0-20PPm 0-20, 100PPm 0.5PPm ≤ 30 seconds Combustible gas detector / alarm EX 0-*LEL 0-*LEL 1% ≤ 30 seconds A portable gas detecting instrument more details please contact us
