Orion™ Versa Star pH / LogR Measurement Module
The Orion™ Versa Star pH / LogR Measurement Module enhances the capabilities of your pH meter, enabling precise pH, mV, ORP, and LogR temperature measurements. Designed for versatility, this module can be easily integrated into any Thermo Scientific™ Orion™ Versa Star meter, which features four customizable channels accommodating interchangeable measurement modules.
Key to the Orion™ Versa Star pH/LogR module is its innovative LogR temperature technology. This feature utilizes the glass-bulb of most pH electrodes to simultaneously measure pH and temperature at the same sampling point—particularly suitable for handling small sample volumes or challenging-to-clean samples.
pH/Temperature Module Features:
- Up to five-point pH calibration with automatic recognition for USA/NIST™ and DIN buffers.
- Calibration editing capability allows fixing of calibration errors without the need for complete recalibration.
LogR Technology Features:
- Includes advanced electrode diagnostics for enhanced reliability.
- Temperature compensated pH readings without the requirement of an external temperature sensor.
