MICROSENSE portable multi gas detector (1 to 5 gases)

The gas detector is designed for measuring concentrations of flammable gases, the volume fraction of oxygen and carbon dioxide, as well as the volume fraction of toxic gases (hydrogen sulfide, carbon monoxide, chlorine, hydrogen cyanide, ammonia, sulfur dioxide, nitrogen oxide, nitrogen dioxide). The devices can be used in the coal, oil, gas and power industry, metallurgy, etc.

The number of controlled gas components: from 1 to 5 (depending on the modification).

Marking Р0 Ex ia I P0 X / 0 Ex ia IIC T4 X.
