Gas analyzers of SGOES modification SGOES, SGOES-2 (further SGOES) determine the presence of the main types of hydrocarbons and measure the pre-explosive concentrations of methane, propane, butane, isobutane, pentane, cyclopentane, hexane, cyclohexane, heptane, ethane, ethylene, propylene, acetone vapor, benzene, ethyl benzene, toluene, xylene, methyl tert-butyl ether, ethyl, methyl or isopropyl alcohols in a mixture with nitrogen or air, as well as for monitoring the gassing of the working area with real industrial vapors proxy petroleum products (gasoline, kerosene, diesel fuel, mineral spirits, and the like).

SGOES gas analyzers are manufactured in explosion-proof design and are certified for operation in explosive environments.

SGOES are used as part of automated alarm systems or as stand-alone gas analyzers for combustible gases and vapors.
