Module.

The 856 Conductivity Module has the following characteristics:

￭ Operation

A touch-screen Touch Control or a high-performance PC software is

used for operation.

￭ Dosing

Dosinos or Dosimats can be used for dosing.

￭ MSB connectors

Four MSB connectors (Metrohm Serial Bus) for connecting dosing devi-

ces (Dosimat with exchange unit or Dosino with dosing unit), stirrers,

titration stands and Remote Boxes.

￭ USB connectors

Two USB connectors, with which devices such as printers, PC key-

boards, barcode readers or additional control instruments (USB Sample

Processor, Titrando, Dosing Interface, etc.) can be connected.

￭ Measuring interface

One measuring input for a conductivity measuring cell with integrated

temperature sensor.

￭ MEAS

The following measuring modes can be selected for measurements:

– Cond (conductivity measurement)

– T (temperature measurement)

￭ CAL

Calibration.

– Cond (determination of the cell constant of a conductivity mea-

suring cell)

￭ Dosing commands
