Oxygen analyzer IKTS-11



Oxygen analyzer IKTS-11  is designed for fast, reliable, precise and continuous measurement of oxygen concentration  in flue gases and in systems of preparation and transportation of the coal dust fuel.


The use of the IKTS-11 gas analyzer leads to the following results:

  • Raising the efficiency of fuel combustion;
  • Reducing emissions of СО and NOx;
  • Ensuring safety from self-ignition under conditions of coal production.


Reliable and simple design

  • Inexpensive and reliable serial sensor based on zirconium ceramics (ZrO2)
  • High speed of operation and high precision of measurements (Т90=10 s)
  • Availability of a parallel current output
  • Customized choice of a probe depending on the environmental conditions
  • Control over СО concentration (optional)
  • Calculation of СО2 concentration and efficiency (optional)

Design and principle of operation

A solid electrolyte sensor is used in the gas analyzer based on zirconium-containing ceramics (ZrO 2)

The probe is installed in the gas duct.

О2 sensor is installed in the measuring module of the probe outside the gas duct.

Oxygen concentration is determined from the difference between static and dynamic pressures in the probe.

The measuring module is installed in a box (safety degree IP66). It is installed at the distance of up to 20 m from the probe.

Box IP66

Dimensions 154х60х110 mm.

Weight without probe is 4 kg.

The device is compact and has one current output. The indicator of О2 concentration is in the device. The measuring module has a tie-in connection врезке (angle adjustment is up to 360 degrees). Setting of the current output and calibration are conducted by using a remote control.

The small-sized IKTS-11.M is the most affordable device in the product line of oxygen gas analyzers.
