Care and Maintenance

Your Palintest direct-reading photometer is designed to give long and trouble-
free operation. To ensure you get the best out of this photometer, please read
these instructions carefully and follow the procedures recommended.
The photometer is suitable for use in both the plant room or for portable
use at the waterside. It is sturdy and robust but should always be regarded
as a scientific instrument. Treat it in the same way that you would a watch
or a camera. It is waterproof (IP67 rated) but careless use will almost
certainly result in damage or reduce the life of the instrument.
Here are 10 hints on keeping the photometer clean, free from contamination
and in good working order :-
1 Prepare your workplace before use. Make sure that you have enough
space to work with the photometer and with the reagent systems.
2 Do not pour out samples or prepare the tests directly over the instrument.
Remember to cap the tube before reading in the instrument.
3 Always cap the test tubes after preparing the blank and test sample.
4 Wipe test tubes on a clean tissue to remove drips or condensation
before placing in the photometer.
5 Do not leave tubes standing in the photometer test chamber. Remove
the tubes immediately after each test.
6 Immediately wipe up any drips or spillages onto the instrument or into the
test chamber with a clean tissue.
7 Keep the instrument clean. Clean the test chamber regularly using a
moistened tissue or cotton bud.
8 Keep the instrument away from all chemicals and cleaning materials. Do
not place the instrument on top of chemical drums or barrels.
9 Keep the instrument in a clean, dry place when it is not in use. Keep it
on a clean, dry bench away from chemicals, place it in a storage
cupboard or keep it in a carrying case.
10 Keep the carrying case (where supplied) in a clean, dry condition. Make
sure that any solutions which have spilled or drained into the carrying
case are dried up before the case is closed up and the instrument is put
away.
