Combustible gas alarm gas alarm toxic gas alarm gas leakage alarm gas alarm ① portable hazardous gas detection alarm instrument use classification sensor, measuring circuit, display, alarm, rechargeable battery, pump assembly in a shell, integrated instrument, compact and lightweight, easy to carry, pump suction sampling can be detected anywhere. ? Pocket Instrument is a portable instruments, general pump diffusion sampler, battery-powered, small volume. ② fixed hazardous gas detection alarm device such instrument is fixed in the field, continuous automatic detection of the corresponding harmful gas (vapor), harmful gas gauge automatic alarm, some can also be automatically controlled exhaust fan. Fixed instruments into one and split two. ? Integrated fixed hazardous gas detection alarm: portable instrument is installed in the field, 220V AC power supply, continuous automatic detection and alarm, multi-diffusion sampling. ? Split fixed hazardous gas detection alarm: alarm sensor and signal transmission circuit assembly in an explosion-proof housing, commonly known as the probe installed in the field (hazardous locations); second part, including data processing, secondary display, control and power assembled into the controller, commonly known as a secondary instrument, installed in the control room (a safe place). The probe diffusion sampler detect secondary instrument display alarm. Gas alarm by the measured object and the sensor principle classification ① combustible gas alarm (referred to as the measured burst instrument, an instrument that detects a variety of combustible gases)? Catalytic combustion combustible gas alarm detector, detection of combustible gas. ? Infrared combustible gas alarm detector to detect a variety of combustible gases (filter technology). ? Semiconductor combustible gas alarm detector, to detect a variety of combustible gases. ?
