Reliable measurement results under tough conditions with ZIRKOR oxygen analysers from SICK

The new range of oxygen analysers in the ZIRKOR series from SICK Automation are extremely rugged and combine high quality with innovative performance. To optimise combustion, the easy to operate and completely reliable precision devices are designed for combustion measurement, which is taken directly after combustion so the oxygen value can be perfectly adapted to the fuel.

Reliable oxygen measurement is just as important for controlling an optimised combustion process as it is for emissions monitoring. In one of the toughest applications of industrial process automation, the analyser must be extremely resistant and easy to integrate. Optimal combustion however, relies on perfect dosing. Too little oxygen will result in incomplete combustion and, therefore, increased CO emissions. Too much oxygen, on the other hand, leads to very high heat loss via the exhaust gas.


Combining high quality and innovative performance, the ZIRKOR range of oxygen analysers from SICK provides an oxygen reference value for emission measurement to ensure reliable, measurable results.

The ZIRKOR series provides an oxygen reference value for emission measurement in order to ensure reliable measurement results. There are three versions available, ZIRKOR100 for smaller plants, ZIRKOR200 for large combustion plants, and ZIRKOR302 for adjustment without test gas.

Tough performance – easy to operate – precise analysis

The ZIRKOR100 is extremely rugged thanks to its innovative cell technology. The integrated cell diagnosis function keeps maintenance work to a minimum and all important information can be accessed via ZIRKOR Remote.

The ZIRKOR200 is a high-tech analyser with simple connection options. It can work in ambient temperatures of up to 1 600° C without any problems and calibrates itself automatically. Thanks to its variable probe lengths and a higher number of interfaces, it can be installed in all kinds of plants and applications. The model works in temperatures of up to 600° C and is also certified in accordance with EN 15267.

The main difference between ZIRKOR302 and the other two analysers is its automated calibration using ambient air. The tried-and-tested flow sensor principle does not require any test gases for this calibration and ensures a continuous, exceptionally precise measurement even at high temperatures. The analyser is available with an optional integrated measuring gas pump or an ejector powered by compressed air.
