Oxygen Analyser

Oxygen Analyser (%) - OPM 8000

Paramagnetic analyser | Analysis of O2 in % level

General

The OPM 8000 Oxygen Analyser (%) manufactured by Orthodyne meets the requirements of industrial gas production. It includes the Paramagnetic sensor technology.

Principle

The automatic manufacturing process is capable of very high precision leading to levels of quality and reproducibility beyond anything that is currently available on the market.

With the possibility to set individual measuring ranges, it  allows the analyzer to be easily tailored to specific measurement requirements. An outstanding characteristic of this analyzer is its long term stability. In most applications, calibration of the zero-point with ambient air or nitrogen is only required once a month. It is also suitable for measuring rapid changes in the concentration of the sample gas.
