Online zirconia oxygen analyzer OMS420-R

Online zirconia oxygen analyzer OMS420-R

The OMS420 integrated online monitoring system for oxygen concentration and combustion efficiency, manufactured by MRU/Mingyou Company in Germany, is based on the ZrO2 measurement principle. It can be equipped with a Coe sensor to measure the concentration of incompletely burned combustibles, forming a complete online monitoring system for combustion efficiency. The measurement unit is installed outside the flue, and the flue gas is introduced into the measurement unit through a reverse flow pipe. The original flue gas returns to the flue.

The integrated online monitoring system for oxygen concentration and combustion efficiency can choose between timed automatic calibration function and automatic soot blowing function.

characteristic

Compact and sturdy structure

The transmitter can be replaced on-site without the need to remove the sampling probe from the flue

Real concentration measurement in wet state, which can be converted into dry state data

Automatic soot blowing function can be selected

Optional online automatic calibration or manual calibration function

No need for reference oxygen

High precision, long lifespan
