Get high accuracy, premium performance and ultimate flexibility with the Thermo Scientific™ Orion™ Versa Star Pro™ Benchtop Meter with pH / LogR Module. Meet your most challenging applications for pH, mV, ORP and LogR temperature. Easily view measurements on the stunning color display and customize the four meter channels with interchangeable modules. Use LogR technology to measure both pH and temperature using the glass-bulb of most pH electrodes. Log up to 2000 data point sets with time / date stamp and easily transfer calibration and data logs via USB or RS232 to a printer or computer.

This versatile meter has a large, color graphic LCD display. The informative display shows readings, connections, time, date, sample ID, user ID and calibration information.
  • Select from five modules to customize the four channels as you need it — it's versatile for you to configure how you need it for now or for later
  • Anyone can use this meter with its plain language screen prompts, soft keys that update for easy selection and a multilanguage interface that supports English, Spanish, French, Italian, German and Chinese
  • Nonvolatile memory holds up to 2000 data points with time and date stamp
  • Data transfer and updating meter software is easy with two USB and RS232 ports
  • Includes data analysis software for transferring stored results or displaying readings in real time
  • Mix samples without a stir plate with direct control for two Orion Star stirrer probes (096019, sold separately)
  • Included electrode arm and newly designed probe holder make it easier to maintain and place probes into samples
  • Works with almost every AC power source with the included universal power adapter
  • IP54-rated housing handles splashes
  • Three year meter replacement warranty

pH/Temperature module allows:

  • Up to five point pH calibration with automatic recognition for USA/NIST™ and DIN buffers
  • Fixing of calibration errors without a complete recalibration with calibration editing

Module featuring LogR technology:

  • Includes all of the features of the pH module with the added benefits of:
    • The most advanced electrode diagnostics
    • No temperature sensor needed to get temperaturecompensated pH readings
