PROBE MAINTENANCE

PERIODIC MAINTENANCE
CLEANING PROCEDURE
Probe can be compensated for normal contamination by a process of recalibration.
When calibration can no longer be achieved, remove the conductivity probe from the
system for maintenance.
Inspect the probe and the cable. The cable used for the connection to the controller must
be intact and there must be no points of broken insulation on the cable.
Connectors must be perfectly clean and dry.
Rinse the probe with tap water. If a more thorough cleaning is desired, remove the
sleeve and clean the platinum sensors with a non-abrasive cloth or HI7061 cleaning
solution. Reinsert the sleeve in the same direction as before.
Recalibrate the instrument before reinserting the probe in the system.
Note Always recalibrate the instrument when attaching a new probe.
