Maintenance and changing the electrode

5.1

General maintenance instructions

The SensoLyt

®

700 pH/ORP armature works maintenance-free. 

Please read the maintenance of the electrode in the relevant operating 
manual of the electrode.

5.2

Replacing the combination electrode

Warning

Contact with the sample can lead to danger to the user! 
Depending on the type of sample, suitable protective measures 
must be taken (protective clothing, protective goggles, etc.).

Caution

If the glass of the pH electrode breaks, there is a danger of cuts 
from the splinters of glass!

If it is necessary to replace an electrode, proceed as follows:

1

Unscrew the protective hood from the armature.
