User Guide

- Air bubbles also disturb measurements and the probe should be

installed in such a way as to minimize them.

Note: It is always recommended to keep at least one spare probe

handy. When anomalies are not resolved with a simple mainte-

nance, change the electrode (and recalibrate the controller) to see

if the problem is alleviated.

Note: Ensure that the probe is installed in such a way that it perma-

nently lies in the solution whether in the tank or the circulation

pipe.
