Paramagnetic oxygen analyzer PM700

The paramagnetic oxygen analyzers of series 700 have been designed for precise and quick measuring results in percent levels. The measuring range of the oxygen level is from 0.01% …99.99%. The instruments  of series 700 are the best in class of high performance oxygen analyzers, they are suited for measuring of oxygen purity.

Further applications are for example facilities with slow or biological conversion of oxygen.

The measuring cell of the analyzer compensates changes in pressure and temperature.
