The measuring interface contains the following measuring inputs:
￭ Cond. Cell for a conductivity measuring cell with integrated tempera-
ture sensor
3.5.1 Connecting a conductivity measuring cell
Various conductivity measuring cells can be connected to the 856 Con-
ductivity Module. The 5-ring conductivity measuring cell with integrated
temperature sensor can be connected directly to the Cond. Cell measur-
ing input. You will need the 6.2103.160 adapter box for older Metrohm
conductivity measuring cells, with or without temperature sensor.
The selection of the conductivity measuring cell depends on the measur-
ing range.
Connect the conductivity measuring cell as follows:
1 Insert the plug of the conductivity measuring cell into the Cond. Cell
socket of the 856 Conductivity Module.
Take care to ensure that the marking on the plug matches the mark-
ing on the Conductivity Module as shown in the figure.

Connecting older models
Connect older models of the conductivity measuring cell as follows:
1 Connect the adapter box to the Cond. Cell socket of the 856 Con-
ductivity Module.
