Measurement Modules
The V
ERSA
S
TAR
meter has four channels that can be configured in any combination using
V
ERSA
S
TAR
measurement modules. The type of module connected to the channel will define
the measurement capability of that channel. Measurement modules are automatically
recognized by the meter and can be added or removed from a channel at any time. Five V
ERSA
S
TAR
modules are available for pH, pH/ISE, pH/LogR, conductivity and dissolved oxygen.
Module Measurement Capabilities
The table below shows the module part number, module label shown on the top tab and
measurement modes. All measurements include temperature.
