Model:      ZRM (Transmitter)
                   ZFK (Detector)

This oxygen analyzer is used to continuously measure oxygen concentration in combustion exhaust gas of industrial boilers or furnaces, and is ideally suited for combustion monitoring and control.

The detector (ZFK) used with the analyser is directly inserted into objects measured, eliminating the need for a sampling device and provides quick response.

The converter (ZRY) features 3 measuring ranges, one touch calibration and NEMA4 housing.

Comparing to the current converter (ZRM) this ZRY is recognized as economical type with simple functions.
