The calibration of conductivity sensor is the key operation to ensure the measurement accuracy. Its core is to correct the measurement deviation of the sensor through the standard solution of known conductivity. The following are common calibration steps, which are suitable for laboratory and industrial online sensors.

To calibrate a conductivity sensor: clean the electrode, immerse it in a standard solution of known conductivity, let the reading stabilize, then confirm the value so the instrument can calculate a correction factor. Two-point (or multi-point) calibration is recommended for most applications because it corrects the full measurement curve, not just one value; single-point calibration is only accurate enough for quick routine checks between full calibrations. The complete procedure is below.

A conductivity sensor is a device that measures how well a liquid conducts electricity by detecting dissolved ions. Higher ion concentrations produce higher conductivity readings. These sensors are widely used in water treatment, chemical processing, pharmaceutical manufacturing, and industrial process control.
