The 875 KF Gas Analyzer enables you to measure trace levels of water in a variety of gases by means of coulometric titration.

Thanks to the built-in evaporator, liquefied gases can also be analyzed.

Gases that can be analyzed with the 875 KF Gas Analyzer include:

  • natural gas and liquefied petroleum gas
  • petrochemicals: propane, propene, butane, butene, butadiene
  • chlorinated hydrocarbons: methyl chloride, ethyl chloride, vinyl chloride
  • refrigerants: CFC, HFC, and CHC compounds.
  • other gases: dimethyl ether, hydrogen, nitrogen, carbon dioxide, and others

A system built to last

The 875 KF Gas Analyzer comes with a series of features that make the analysis robust and safe: All components are contained in one housing, and the electronic parts and the gas-carrying parts of the instrument are physically separated. In addition, this instrument can handle gas pressures up to 40 bar.

Furthermore, the 875 KF Gas Analyzer is highly dependable: a built-in oil filter makes sure that residual oil is removed from the gas, and the inlet filter prevents particulate matter from clogging up the piping.
