Honeywell has added oxidation reduction potential (ORP) measurement — a means to minimise corrosion in power plant equipment such as turbines and piping — to its HPW7000 High-Purity Water Measurement System.
The HPW7000 High-Purity Water Measurement Systems with ORP measurement should enable plants to better maintain critical equipment, reduce capital expenses and lower chemical usage, Honeywell says.
The HPW7000 is used in applications such as boiler feedwater systems in municipal utilities and large industrial plants that produce electricity from on-site power plants.
Its flow chamber and electrode mounting has been used for more than 10 years to simplify installation and calibration while providing highly accurate pH level readings, Honeywell says.
Adding the ORP electrode gives plant chemists, plant managers, maintenance engineers and safety and reliability engineers a more-accurate picture of oxidation levels in high-purity water systems where the conductivity of the water samples is less than 10 microsiemens per centimeter (uS/cm), the company says.
