1. Safety instructions
The electrode may only be used with dilute
acid and alkali solutions (max. 10%).
Do not allow the sensor to come into
contact with viscous organic liquids such
as oils, glycerine or glycols.
Do not let the test surfaces of the electrode
(graphite rings and discs) come into
contact with hard objects.
Do not allow the electrode housing to come
into contact with organic silicones.
The electrode must always be stored at
temperatures in the range between +10°C and
+35°C.
2. Description
Sensor box including conductivity electrode for
measuring conductivity in aqueous solutions in
the units mS/cm.
Conductivity electrode with integrated Pt100
temperature sensor.
