Features and Benefits

• Each conductivity probe is tested to obtain its unique four-digit electrode constant. The electrode constant is used together with GLI's DRY-CAL calibration method to ensure high accuracy of conductivity probe measurement;

• This series of conductivity probes offers a variety of material options, with high temperature response performance, capable of handling any measurement range from ultrapure water to boiler water, as well as various harsh environments;

• Multiple conductivity probe installation methods: compression mounting type, non-metallic general-purpose type, boiler/condensate type, and sanitary flange type.

Calibration Method

The conductivity measurement electrodes are calibrated using the DRY-CAL calibration method. Each conductivity electrode undergoes conductivity slope measurement and temperature offset measurement at the factory, and each conductivity probe is marked with its factory calibration data. Operators only need to input the calibration data during installation, and the conductivity electrode is ready for operation.
