EN-600 Explosion proof hydrogen analyzerDetailed product description：

The EN-600 explosion-proof hydrogen analyzer operates based on the physical property that different gases have different thermal conductivities, and the thermal conductivity of mixed gases varies with the content of the measured components. The design and manufacturing of the instrument fully comply with the provisions of the national standard GB3836 1-2000 2-2000 3-2000 on "Explosion proof Electrical Equipment for Explosive Environments, Explosion proof Electrical Equipment" d ", and Intrinsic Safety Electrical Equipment" i ", and have been recognized by the national level instrument explosion-proof safety supervision and testing station. The instrument series has a combination structure of "explosion-proof" and "intrinsic safety", with the explosion-proof mark of "Exdib Ⅱ CT6" and the explosion-proof certificate number of "GYB03282".
The instrument adopts stable and reliable thermal conductivity gas sensors and microprocessing technology, with functions such as large screen LCD display, upper and lower limit alarm, standard signal output, and relay contact alarm output. Suitable for Zone 1 and Zone 2 flammable and explosive hazardous areas with explosive and temperature groups T1 to T6 formed by combustible gases, vapors, and air.
