3.5 Reference electrode
3.5.1 Construction
The complete reference electrode (RE)
22
comprises two parts:
6.0728.0X0 Ag/AgCl reference system (101)
with ceramic diaphragm type D, diameter = 1 mm
6.0728.020
Reference system: Ag/AgCl/
c
(KCl) = 3 mol/L;
supplied in a holder filled with
c
(KCl) = 3 mol/L
as standard
6.0728.010 Reference system: Ag/AgCl
supplied dry (option)
6.1245.010 Electrolyte vessel (102)
with ceramic diaphragm type D, diameter=3 mm; holds
a second electrolyte solution (bridge electrolyte) and
thus forms with the 6.0728.020 Reference system a
complete reference electrode in the so-called double
junction construction.
The construction of the reference electrode and the designations of the individual
parts are shown in
Fig. 13
