As is stated in the brochure: "The 871CR Series Sensors measure the conductivity or resistivity of a solution. These sensors, together with an 870ITCR Intelligent Electrochemical Transmitter or an 875CR Intelligent Electrochemical Analyzer, are used in a broad range of applications including critical ultrapure water resistivity measurements found in the semiconductor industry and conductivity measurements used in power and pharmaceutical water measurements."
Is one of these sensors and the electrochemical analyzer the equipment you are looking for?
