PROBE MAINTENANCE

PERIODIC MAINTENANCE

Inspect the probe and the cable. The cable used for the connection to the meter must be intact and there must be no points of broken insulation on the cable or cracks on the probe stem or bulb.

Connector must be perfectly clean and dry. If any scratches or cracks are present, replace the electrode. Rinse off any salt deposits with water.

CLEANING PROCEDURE

For better accuracy in measurements and to ensure a good performance of the probe, a frequent cleaning is recommended.

For this purpose, soak it in Hanna HI 700661 Cleaning Solution for

5 minutes.

Note: For particular dirty (as for example protein, oil or grease) see the "Accessories" section for Hanna specific solutions.

Note: After cleaning the probe, it is recommended to recalibrate the meter. If it is not possible to calibrate, the probe has to be replaced with a new one.

Note: For field applications, it is always recommended to keep a spare probe handy. When anomalies are not resolved with simple maintenance, change the probe and recalibrate the meter.
