Solvent Dip
Dip the sensor into a solvent such as
isopropyl alcohol. Remove solvent using a
clean cloth. Do not use solvents which are
known to be incompatible with the plastic of
the sensor. This method removes organic
coatings. After dipping, rinse sensor with
water.
Physical Cleaning
Use a rag, acid brush, or tooth brush to
remove especially thick scales and
accumulations. Take caution in cleaning the
glass pH electrode, if present, to prevent
glass breakage.
When mechanically cleaning the sensor, always
use a soft bristle brush in order to avoid
damaging the insulating coating on the
solution ground (i.e., the metallic collar
around the measuring electrode if present).
This coating is only present on the outer
diameter next to the reference junction and
must be intact for the reference diagnostics
to function properly.
