9091 Dissolved Hydrogen Analyzer

The Waltron 9091 Dissolved Hydrogen Analyzer is the industry standard for continuous measurement of dissolved hydrogen in water. Measurement is microprocessor based and uses a potentiostatic three electrode system.

Important application points include primary loop of nuclear power plants, boiler beed-water in thermal power plants, denitrification of drinking water, and catalytic reduction of oxygen on noble metal surfaces in water treatment plants. The dissolved hydrogen concentrations within the water/steam loop of a power plant gives quantitative and qualitative evidence of the rate of corrosion, corresponding to the buildup or destruction of the protective oxide layer inside pipes and boiler tubes.
