CARE AND MAINTENANCE

The photometer is designed to give long and trouble-free operation. Care must
be taken, however, to avoid test solutions being spilt over the instrument, and
to prevent contamination of the instrument. Spillages or moisture should be
wiped off immediately with a dry cloth. On no account should solvents or
abrasive materials be used to clean the instrument. Care should be taken to
keep the test chamber clean.

Cleaning the Optics

Any build-up of dirt or deposits may interrupt light transmission and affect
readings.
To clean the optics, undo the two screws to remove the optics base plate.
Gently clean the internal surfaces of the optics with a soft, non-abrasive cloth.
Deposits may be removed with a slightly dampened cotton bud. Replace the
optics base plate and re-fasten the screws.
The photometer is fitted with long-life light sources and contains no user-
serviceable components. If the instrument requires servicing or repair, this can
be arranged through our Technical Services Department.

performance. To arrange a service of the instrument, contact Palintest Technical
