The 867 pH Module has the following characteristics:
Operation
￭
A touch-screen Touch Control or a high-performance PC software is
used for operation.
Dosing
￭
Dosinos and Dosimats can be used for dosing. Dosing is required for
standard additions and when auxiliary solutions are to be dosed.
MSB connectors
￭
Four MSB connectors (Metrohm Serial Bus) for connecting dosing devi-
ces (Dosimat with exchange unit or Dosino with dosing unit), stirrers
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 each for:
– a potentiometric electrode (pH, metal or ion-selective electrode)
– a separate reference electrode
– a temperature sensor (Pt1000 or NTC)
– a polarizable electrode
– an iConnect (measuring interface for electrodes with integrated
data chip, so-called iTrodes)
The following measuring modes and commands are supported:
MEAS
￭
The following measuring modes can be selected for measurements:
– pH (pH measurement)
– U (potentiometric voltage measurement)
– T (temperature measurement)
– Ipol (voltametric measurement with selectable polarization cur-
rent)
– Upol (amperometric measurement with selectable polarization
voltage)
– Conc (concentration measurement)
