FSUE “SPA “Analitpribor” is one of the leaders of gas-analysis instrument engineering in the Russian Federation. Production of gas-analysis equipment is from 1960.
АКВТ-01, -02, -03 - fixed gas analyzers of combustion modes optimization

Designed for maintenance of optimum relationship fuel-air due to continuous monitoring of content of oxygen (АКВТ-01;-02) or oxygen or carbon oxide АКВТ-03) in order to optimize combustion processes and to prevent incomplete combustion.


Application:  АКВТ-01, АКВТ-03 (general purpose industrial version) – at heat-power engineering plants, in boiler units of heat electropower stations, hydroelectric power plants and different boiler houses, as well as in industrial furnaces, in metallurgy, oil processing, mechanical engineering and other branches of industry. АКВТ-02 (explosion-proof version) – mounting in hazardous areas on waste incinerators of oil processing plants and similar objects.


Type of gas analyzer - fixed.

Principle of operation - electrochemical (based on ZrO2) and thermocatalytic based on СО.

Sampling - diffusion (АКВТ-01, АКВТ-02); forced (АКВТ-03).


Gas analyzers are powered from ac voltage mains 220 V, 50 Hz.

Gas analyzer warm-up time not more 4h.

All versions have “dry” relay contacts (220 V, 2,5 А), unified current signals (0 - 5) and (4 - 20) mА and communication channel RS 485 MODBUS.RTU to connect external devices (PC).


Gas analyzers consist of:

   - АКВТ-01: power supply and processing unit (PPU) and probe fixed on chassis;

   - АКВТ-02: monoblock with probe immersible into gas stream;

   - АКВТ-03: power supply and processing unit (PPU) and sensor unit (SU).

   In АКВТ-03 maximum length of connection cable between PPU and SU not more than 50 m.

   In АКВТ-01 the possibility of PPU and SU separation at a distance up to 125 m (on special order).
