Cleaning the Sensor Cap
Leave the cap on the sensor! 1.
Rinse the sensor with clean water from a squirt bottle or spray bottle. 2.
Gently wipe with a soft cloth or brush if biofouling is present. 3.
If extensive fouling or mineral build-up is present, soak the cap end in 4.
vinegar for 15 minutes, then soak in deionized water for 15 minutes.
Do not use organic solvents—they will damage the foil. Do not
remove the cap from the sensor prior to brushing.
After cleaning the sensor, perform a 2-point user calibration.
Cleaning the Optical Window (Perform only when changing the cap.)
Remove the cap and gently wipe the window with the supplied lens wipe.
Caution: Do not wet the lens area with water or any solution.
Cleaning the Sensor Body
With the sensor cap installed on sensor, gently scrub sensor body with a
soft brush. Soak in vinegar and DI water to remove mineral deposits or
extensive fouling as in step 4, above.

Storage
Prior to installation: Store in factory supplied container
Installed: Store as per requirements of other installed sensors, for
example, pH, if installed. Keep or store in a moist environment, such as
the recyclable calibration and storage sleeve or the optional calibration and
storage vessel.
Replacing the Sensor Cap
The sensor cap has a 1-year life after the TROLL 9500 instrument takes
its first RDO sensor reading. Replacement caps are available from In-Situ
Inc. or your authorized In-Situ distributor.
Pull the used sensor cap off of the sensor, without twisting. 1.
Remove the existing o-rings from the sensor. 2.
Use a lint-free cloth to remove any moisture from the sensor body. 3.
Note: Ensure that there is no moisture in the o-ring grooves.
Avoid touching or cleaning the lens with anything other than the
supplied lens wipe.
Use your finger to apply a layer of lubricant around the o-ring grooves. 4.
Place the o-rings on the sensor. Apply another thin layer of lubricant to
the o-rings and grooves
Note: Do not transfer grease to the lens or sensor pins.
Clean the lens on the sensor with the wipe provided in the kit and allow 5.
to dry thoroughly. Inspect for scratches or dirt.
Remove the new cap from its sealed packaging and attach it to the
6.
sensor, being careful to press firmly, without twisting, until it seals over
the probe body. Make sure that the o-rings are not pinched or rolled
between the cap and sensor.
Perform a 2-point calibration as described in the RDO Instruction
7.
Sheet or TROLL 9500 Operator's Manual.
Insert the 9500 instrument with
attached RDO sensor into its Cal cup
and tighten.
For the sub-4 in model, attach
the red plug to seal the top of the
restrictor.
Alternatively, place a sleeve inside
restrictor. Add a small amount of
water or pH buffer to keep moist.
