FIELD: heat power engineering; device for analysing gases in furnaces of boiler units and industrial furnaces. SUBSTANCE: proposed gas analyzer has solid electrolyte cell with platinum electrodes, housing, heater, units to deliver gas to be analyzed and reference gas, compensating thermocouple electrically connected in opposition to cell. Inner electrode of solid electrolyte cell is used as of thermal electrode. Second thermal electrode made of material providing tolerable measurement error is mechanically pressed to first electrode. EFFECT: enhanced accuracy of gas analyzing. 1 dwg
