Maintenance
Storing the pH electrode in deionized water (or any solution lacking sufficient
KCl) will cause the electrode to drift and require increasingly frequent calibra-
tion.
Conductivity Sensor Maintenance
The conductivity sensor requires only minimal maintenance and is field
replaceable. The sensor element is made of graphite and is resistant to most
chemicals. The thermistor is housed in stainless steel and is also resistant to
most chemicals.
• Rinse the sensors in clean water after each use. These sensors can be
stored dry.
• Should any buildup become evident, the sensors should be cleaned. A
mild soap detergent, with some agitation, is usually sufficient to effectively
remove most deposits. Rinse and recalibrate.

Temperature Sensor Maintenance
Do not attempt to remove the temperature sensor. The temperature sensor is
secured internally and can only be removed at the factory. Removal will
invalidate the probe warranty. Should the temperature sensor need to be
replaced, contact the factory or dealer.
