Cleaning the HI764113 Probe Body

• Rinse the probe with clean water to remove debris from around the probe body; wipe with a soft

cloth. Unscrew and remove the protective shield and set aside. Ensure weeds, debris, or other

materials are not coating the protective guard as this will block sample circulation preventing

sample from reaching the active measurement surface.

• The exterior of the HI764113 can be cleaned by wiping the exterior surface with a aqueous-

soapy mixture and gently rubbing the exterior surface. Rinse with clean water.

The Stainless steel guard can be cleaned and polished with a cleaner suitable for stainless steel

cookware or appliances. Avoid chlorine bleach containing products.

Inspection

• Routinely Inspect probe for biofouling. Carefully inspect the probe body and Smart Cap.

A scratch in the black protective layer on the Smart Cap will affect the calibration (and

measurement). Replace the Smart Cap if the sensing surface has been compromised.

Cleaning the Smart Cap

• Use a mild detergent and a soft bristled toothbrush to clean the Smart Cap.

Rinse the cap with water after cleaning and dry with a laboratory tissue.

Yearly Replacement of the Smart Cap

• Easy to use smart caps contain pre-loaded calibration coefficients that are automatically

transmitted to the probe. The Smart Cap stores data in a RFID tag. If caps are switched between

probes, no information will be lost. Smart Cap installation dates are easily tracked via the Probe

info screen and when powering , the meter displays remaining cap life.

• Rinse the probe with clean water to remove debris from around the probe body; wipe with a

soft tissue.
