Thermo Scientific VSTAR-LR - LogR Measurement Module

• Perform up to a six point pH calibration using automatic buffer recognition of NIST, DIN or user-defined buffer groups with choice to manually enter custom buffer values
• Calibration editing option allows individual points to be fixed without a full recalibration
• Customize measurements to show calibration history and pH electrode condition or simplify to show an extra large pH reading
• Module offers a 3-year replacement warranty
• LogR technology uses the glass-bulb of most pH electrodes to measure both pH and temperature at the same location – ideal for small sample volumes and samples that are difficult to clean

Add pH, mV, ORP and LogR temperature measurement capabilities to your Thermo Scientific Orion Versa Star meter using the Thermo Scientific Orion Versa Star pH / LogR Measurement Module. Each Orion Versa Star meter has four channels that can be customized with interchangeable measurement modules. The Orion Versa Star pH/LogR module offers LogR temperature technology that uses the glass-bulb of most pH electrodes to measure both pH and temperature at the same location – ideal for small sample volumes and samples that are difficult to clean.

Preparation

1. Prepare the universal power adapter, install the meter-attached electrode stand and verify that the pH/LogR module is connected to the meter. If it is not connected, insert the module into two available channels on the back of the meter.
2. Prepare the electrodes as instructed in the electrode user manuals. For improved movement and control, place the electrodes into the electrode stand.
3. Connect the pH electrode cable to the BNC input on the module and ATC probe cable to the 8 pin MiniDIN input on the module. An ATC probe can be used when calibrating LogR temperature or as the direct temperature source.
