Sensors Analyze Sulfide Levels in Water and Waste Treatment Plants
February 8, 2010
The sensors provide accurate, reliable analysis of sulfide levels that helps ensure proper water treatment. Available as an insertion style sensor or a valve retractable style sensor, they are fully re-buildable and feature a 316 stainless steel body that incorporates the sensing element, a temperature module and a signal conditioner with cabling. Sulfides are also commonly present in sewage and wastewater treatment plants. The sensors pIon electrode cartridge measures the activity of “free” Sulfide ions in solution in concentrations from 0.01 to 32,000 ppm over a pH range from 11-14 pH. The pIon can measure Sulfide ions over a wide temperature range of 0 to 80 degrees C. Both sensors use replaceable electrode cartridges, which can be selected to measure pH, ORP, dissolved oxygen, conductivity and resistivity. They are constructed in a variety of configurations and materials to support diverse industries. The application specific sensor cartridges utilize field proven construction materials that are selected for long life and accuracy. The sensors can be integrated with the manufacturer’s analyzer to provide automatic pH compensation for a total sulfide measurement system.
