Replacing the glass body with the cathode
NOTICE
Polishing the cathode can cause impaired function or total failure of the sensor.
►
Do not clean the cathode mechanically.
If the cathode is coated, replace the glass body.
1.
Hold the sensor vertically and unscrew the shaft sleeve.
2.
If the membrane body remains on the glass body and not in the shaft sleeve, remove it from the
glass body.
3.
Flush the glass body, along with the anode and cathode, using distilled water.
4.
Pull the used glass body out of the holder.
5.
Dry the inside of the electrode holder.
6.
Plug a new glass body (from the membrane kit) into the holder so that it fits. Ensure that you do
not damage the electrical contact pins.
7.
Fill the membrane body with electrolyte (see preceding section), then screw the shaft sleeve back
on.
