5. Operation
5.1.1 Maintenance procedure for the GS-[….]DP type sensor (Cont’d)
4.
To prevent contamination from the old electrolyte, rinse out the gas sensor interior twice
with a small amount of fresh electrolyte (fig. 5.1.5)
5.
Hold the gas sensor with the electrode pointing upwards. Ensure that the new O-ring has
the appropriate colour and that, if applicable, the silicon seal is in place. (fig. 5.1.6)
6.
Place a drop of fresh electrolyte carefully on the measuring electrode (fig. 5.1.7).
7.
Place a new membrane onto the measuring electrode. Due to the hygroscopic behaviour of
the electrolyte, the membrane will easily stay in place (fig. 5.1.8).
Position the membrane holder and screw on the membrane holder cap, which should be
firmly tightened (fig. 5.1.9).
8.
Holding the sensor with the membrane pointing downwards, pour fresh electrolyte from
the dispenser bottle into the electrolyte supply opening until the electrolyte in the sensor
reaches the ‘MAX’ level (fig. 5.1.10).
If necessary, wipe clean the electrolyte supply opening with dry paper tissue (fig. 5.1.11).
9.
Remount the vent plug (fig. 5.1.12), cover the vent plug with a new adhesive membrane
and gently shake the sensor to dislodge any air bubbles which may have formed around
the electrode.
We recommend the following time schedule for changing the electrolyte:

The type of electrolyte and membrane to be used is indicated on the
label of the gas sensor. The code EL-[ .…] indicates the electrolyte type
and the code M-[.…] indicates the membrane type.
Depending on the type of sensor the O-ring’s will either be white or
black. When replacing the O-ring’s please make sure to replace it with
an O-ring of the same colour.
