Diaphragm:
The diaphragm makes the electric connection between re-
ference system and sample� Additionally it should prevent
the spoiling of the reference electrolyte by the
measured medium�
Ceramic diaphragm
Porous ceramic rods ensure low leak rates�
Application:
General applications in clean till lightly
soiled media�
Joint / movable joint
The roughened surface between the cut glass
of the electrode and a cut glass sleeve permits
a electrolyte ow of several ml / h�
Application:
low-ion or heavily soiled samples
Pellon diaphragm
A permeable diaphragm made of Pellon texture
is used for fast response times and stable
measuring values
Application:
Clean till lightly soiled media�

Electrodes are consumption objects. Lifetime under careful treatment: >2 years; warranty: 12 months
Reference electrolyte:
The reference electrolyte oers a constant voltage of the
reference system and makes the electrical connection
between sample and reference electrode�
Liquid electrolyte
Mainly 3 mol / l KCl is used� Liquid electrolytes oer fast
response times in general and can be replaced if contami-
nated�
Gel electrolyte
The electrolyte is solidied for low-maintenance electrodes
able to measure irrespective to its position� Under normal
measurement conditions no noticeable electrolyte leakage
is observable�
Electrodes with S7 connection:
The electrodes are oered with an S7 industrial screw plug
tted, also known as industrial-S8 Plug head� In contrast to
S7 lab plug head this one is for direct installation in ttings
with PG 13�5 suitable thread�
