Cleaning and Reconditioning the Chloride Sensor
The chloride sensor is considered a pellet membrane ISE. As always, when handling sensors, care should be
taken to avoid damaging the membrane. This sensor can be regenerated by washing with alcohol and/or gently
polishing with fine emery paper in a circular motion to remove any deposits or discoloration, then thoroughly
washing with deionized water to remove any debris.
The sensor may require soaking in the high chloride calibration solution to recover its performance. Soak in
1000 mg/L for several hours or overnight.
