Thermo Scientific
Measurement Modules
The V
S
meter has four channels that can be configured in any combination using
ERSA
TAR
V
S
measurement modules. The type of module connected to the channel will define
ERSA
TAR
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
S
modules are available for pH, pH/ISE, pH/LogR, conductivity and dissolved oxygen.

Preconfigured Meter and Module Options
V
S
meters can be purchased without modules or preconfigured with up to four
ERSA
TAR
modules included. Preconfigured V
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/Dissolved Oxygen) 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.
