9091 Dissolved Hydrogen Analyzer
Brand: Waltron Bull & Roberts, LLC
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 feed-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.
