Sensor Deployment
Sensor Deployment
The cable end of the RDO ® Pro is internally threaded (1¼ - 11½ NPT) and can
be attached to a externally threaded pipe.
When deployed, make sure that the nose cone and thermistor are completely
submerged.
Care and Maintenance
Cleaning the Sensor Cap
1. Leave the cap and nose cone on the sensor!
2. Rinse the sensor with clean water from a squirt bottle or spray bottle.
3. Gently wipe with a soft-bristled brush or soft cloth if biofouling is present.
Use Alconox ® to remove grease.
4. If extensive fouling or mineral build-up is present, soak the cap end in
vinegar for 15 min., then soak in deionized water for 15 min.
Do not use organic solvents - they will damage the foil.
Do not remove the cap from the sensor prior to brushing.
Cleaning the Optical Window
Perform only when changing the cap. See full instructions in the sensor
replacement cap kit.
Do not wet the lens area with water or any solution.
Remove the cap and gently wipe the window with the supplied lens wipe.
Use only the supplied lens wipe for cleaning. Do not use any other wipe
or material.

Cleaning the Sensor Body
With the sensor cap installed on sensor, gently scrub sensor body with a soft-
bristled brush or nylon dish scrubber. Use Alconox to remove grease or other
matter. Soak in vinegar and deionized (DI) water to remove mineral deposits or
extensive fouling as in step 4, above.
Cap Storage
• Prior to installation: Store in factory supplied container.
• Installed: Keep or store in the calibration chamber with the storage cap
attached and a few drops of clean water.
