Ammonia Soaking: When the liquid interface is blocked by silver chloride
can be leaching with concentrated ammonia. The specific method is to
clean the electrode, the liquid vent after immersion in ammonia 10 to 20
minutes, but do not let ammonia into the electrode inside. Remove the
electrode with distilled water to wash, re-add the internal liquid and continue
to use.
Vacuum method: the hose to match the reference electrode fluid interface,
the use of water suction pump, suction part of the liquid through the fluid
interface, remove the mechanical blockage.
Boiling fluid junction: silver - silver chloride reference electrode liquid
interface immersed in boiling water for 10 to 20 seconds. Note that the next
time you boil, the electrode should be cooled to room temperature.
When the above methods are invalid, sandpaper grinding can be used to
remove the mechanical method of grinding. This method may cause the
sand under the grinding into the liquid interface. Causing permanent
clogging.
