3. Maintenance

It is forbidden to separate the housing of the instrument.

In addition to the occasional need to use a damp cloth to wipe, the instrument does

not need to do other maintenance. The shell is made of plastic and is subject to

erosion by some organic solvents such as toluene, xylene and butanone. If this is

the case, immediately wipe the spill onto the shell of such solvents.

Ensure that the electrode is always stored in the appropriate storage solution.

In order to obtain maximum accuracy, any filled or coagulated in the electrode

outside the filling liquid are used to remove the distilled water in time. Always

store the electrode according to the manufacturer's regulations and do not dry

it. If the slope of the electrode drops rapidly, or if the corresponding speed is

slow, the following steps can be used. Depending on the sample, try the

following:

1. For grease, remove the dirt from the surface of the electrode with raw

cotton dipped in acetone or soapy water.

2. If the electrode film is dry, immerse the electrode tip in 0.1M HCl solution

and allow to stand overnight.

3. If protein is accumulated in the membrane, immerse the electrode in the

HCI/pepsin solution to remove the deposit.
