Care and Maintenance
Clean the RDO-X Sensor Cap
1. The cap and nose cone must remain on the probe.
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
minutes, then soak in deionized (DI) water for 15 minutes.
Do not use organic solvents—they will damage the sensing
element. Do not remove the cap from the sensor prior to cleaning.
5. After cleaning, perform a 1- or 2-point user calibration or calibration check.
Clean the Optical Window
1. Clean the optical window only when you change the cap. See full instructions in the
sensor cap replacement kit.
2. Remove the cap and gently wipe the lens with the supplied lens cloth.
Do not wet the lens area with water or any solution. Use only the
supplied lens cloth for cleaning. Do not use any other cloth or
material.
Clean the Probe
With the RDO cap installed on probe, gently scrub the probe with a soft-bristled brush
or nylon dish scrubber. Use Alconox to remove grease or other matter. Soak in vinegar
and DI water to remove mineral deposits or extensive fouling.
RDO-X Sensor Cap Storage
Prior to installation—Store in factory supplied container.
Installed—Store in the calibration chamber with the storage cap attached and a few
drops of clean water.
Replace the RDO-X Sensor Cap
The RDO cap has a 2-year typical life after the sensor takes its first reading.
Replacement caps are available from In-Situ Inc. or your authorized In-Situ distributor.
1. Remove the probe nose cone.
2. Use a lint-free cloth to remove any moisture from the probe.
