9091C Dissolved Hydrogen Analyzer

Description

The Waltron 9091/9091C Dissolved Hydrogen Analyzer is the intelligent choice for continuous measurement of dissolved hydrogen in ultrapure water applications. Measurement is based on a highly-accurate electro-chemical process. The 9091’s potentiostatic technology allows for a much faster response time than amperometric or colorimetric systems, ensuring short start-up times, easy operation, and low maintenance costs. Calibration is automated and the sensor can be mounted separately from the transmitter, allowing for remote control away from hazardous areas. Important application points include primary loop of nuclear power plants, boiler feedwater 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 can provide 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. Options include the online 9091 version and a portable 9091C for online and benchtop applications.
