Portable individual gas analyzer - leak detector DOZOR-S-P

perenpsnoy gazoanalizator 



Application domain

Portable gas analyzers, gas detectors and leak detectors are distinguished by:
а) realizations of periodic control of maximum-possible concentrations in mid air of working zone of harmful substances (СО, NH3, NO, NO2, Cl2, H2S, O2, CO2, SO2);
б) realizations of periodic control to the explosive concentrations of combustible gases and steams in mid air (hydrogen, hydrocarbon gases, pairs of alcohols, oil products, solvents of and other);
в) deliveries of the light and voice signaling under reaching the set values of concentration.

The gas analyzer of DOZOR-S-Pk is supplied exceptionally for control of combustible gases.
