Conductivity/Temperature Sensor Maintenance
1. Dip the sensor's cleaning brush (included with the maintenance
kit) in clean water.
2. Insert the brush at the top of the channels, and sweep the channels
15 to 20 times (Figure
NOTICE: If deposits have formed on the electrodes, use a mild
solution of dish soap and water to brush the channels.
For heavy deposits, soak the sensor in white vinegar to
assist cleaning, then scrub with the cleaning brush after
soaking.
3. Rinse the channels with clean water following the sweepings or
soak.
Conductivity/Temperature Sensor Short-Tem Storage
(Less Than 4 Weeks)
When in regular field use, the conductivity/temperature sensor should
remain installed on the bulkhead in a dry or water-saturated air
environment.
Place approximately 0.5 in (1 cm) of any water (deionized, distilled or
environmental) in calibration cup.
Install the calibration cup on the bulkhead and firmly tighten to prevent
evaporation (Figure 67).
