The electrolyte in conventional silver/silver chloride reference systems must be saturated with silver chloride.
With critical media such as those containing sulphides or proteins, this will result in diaphragm contamination with silver sulphide. This can not happen with InLab® electrodes which have an ARGENTHAL™ lead off and silver ion trap that ensure the electrolyte remains completely free from silver ions. The ARGENTHAL™ reference system also improves service life and measurement accuracy at differing sample temperatures.
The glass shaft provides resistance against organic and corrosive samples. Different cables can be connected to the S7 screw head allowing use with a wide range of meters.
