Measurement Modules

The Versa Star Pro meter has four channels that can be configured in any combination using
Versa Star 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 Versa Star
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
measure modes. All measure modes include the option to also measure temperature.

Preconfigured Meter and Module Options

Versa Star Pro meters can be purchased without modules or preconfigured with up to four
modules included. Preconfigured Versa Star Pro meters will have the modules already
connected with the channels. Any open channels will be covered with blank modules.

1.

VSTAR-PH (pH), VSTAR-ISE (pH/ISE), VSTAR-CND (Conductivity) and VSTAR-RD
(RDO/DO) measurement modules – each connects with one channel.

2.

VSTAR-LR (pH/LogR) measurement module connects with two channels.

3.

Unused channels are covered with blank modules.
