871CC Contacting Conductivity/Resistivity Sensors are used with 873CC, 873RS, 873ACC, 873ARS, 875CR, 870ITCR, and 876CR Electrochemical Analyzers and Transmitters to detect the conductivity or resistivity of a solution. The analyzer applies a low frequency voltage or current across the sensor electrodes in contact with the process fluid. The resulting electrical parameter is sampled, interpreted, temperature-corrected, and displayed by the analyzer.
