Designed for fast, Easy & trouble free start up Oro Electrical conductivity sensors are ideal for measuring the concentration of dissolved solid in water. They are provided with an accurate predetermined factory calibration constant. Conductivity is measured by applying an alternating current to a measuring cell. This cell comprises a glass body supporting two to four platinum plates (also called poles) immersed in a solution. General Features: Measure concentration of dissolved solids in water Accuracy @ 2% FS Available with 1.0 cell constants Rugged design Corrosion resistant material keep electrode spacing Surface area constant so cell constant remains stable for a long period. High resistance to corrosion ensures a long life Requires low maintenance.
