Oxygen Analyzers in the ZIRKOR Series

- extremely rugged and combine high quality with innovative performance -

Waldkirch, February 2017

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.


The Oxygen Analyzers in the ZIRKOR Series

The new oxygen analyzers in the ZIRKOR series

are extremely rugged and combine high quality with innovative performance. The precise devices for combustion optimization are easy to operate and completely reliable. They take measurements directly after combustion so the oxygen value can be perfectly adapted to the fuel.
Reliable oxygen measurement
is just as important for controlling an optimized combustion process as it is for emissions monitoring. In one of the toughest applications of industrial process automation, the analyzer must be easy to integrate and extremely resistant.
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.



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.

is a high-tech analyzer 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 that works in temperatures of up to 600 °C is also certified in accordance with EN 15267.

The main difference between ZIRKOR302

and the other two analyzers is its automated calibration using the 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 analyzer is available with an optional integrated measuring gas pump or an ejector powered by compressed air.
