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 perfor-
mance 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.
