Water AnalyzerThe Model 204 Oil & Hydrocarbons in Water Analyzer accurately measures total hydrocarbons including aliphatic and aromatic hydrocarbons. It has the ability to analytically quantify oil/hydrocarbons in water thanks to an enhanced  Sample Transfer Stripper and a solid state sensor. 

The on-line analysis offered by the Model 204 is economically superior to inaccurate laboratory analyzers where unstable grab samples result in oil deterioration that produce analytical errors.
The liquid sample continuously flows into the analyzer and into the heated Sample Transfer Stripper unit which effectively strips the hydrocarbons from the oil in the water based in part on Henry’s Law.

The advanced transmitter electronics quantifies and displays the values on the back-lit LCD display, 4-20mA output loop and can communicates via RS-485 Modbus. Remote and Web based monitoring and control of the analyzer is available.
