9072 Hydrazine Analyzer
Range: 0-1000ppb
The Waltron 9072 Hydrazine Analyzer delivers automatic, continuous measurement of hydrazine concentration independent of flow in clean water applications. Measurement is based on a highly-accurate potentiostatic electro-chemical principle. The 9072 is used for industrial process monitoring and control of residual hydrazine concentration in boiler feedwater, the primary loop of nuclear power plants, and water treatment plants. The 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.
