Routine pH measurements are quick and easy with the Orion VERSA STAR 80 pH benchtop meters. The large color display is easy on to read and easy on the eyes. Prompts make accuracy and repeatability easy for even the most complicated testing. If you need to add more channels for more or obtain more parameters from the same, simply remove the protective individual channel cover and add the new module.

  • Preventing wasted efforts and time from bad electrodes by offering the most advanced electrode diagnostics
  • Using even less of those expensive samples for testing and still getting accurate pH results since LogR technology allows for temperature-compensated pH readings without a temperature sensor
  • Up to 6 point pH calibration with automatic recognition for USAIST and DIN buffers and electrode identification
  • The time-saving option to fix errors without a complete recalibration with the calibration editing function
  • Customize the display to show only the information you need
  • Change out modules to create the meter you need at any time
  • Anyone can use this meter with its plain language screen prompts, function keys that update for easy selection and a multilanguage interface that supports English, Spanish, French, Italian, German and Chinese
  • Don't miss a reading - AUTO-READ™ locks in the stable reading on your screen, ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals or just once with single-shot mode
  • Non-volatile memory holds up to 2000 data points with time and date stamp
  • Stores up to 10 methods per channel allow for customized procedures to differentiate between tests and/or users
  • Two USB and a RS232 port makes for easy data transfer and updating meter software
  • Includes data analysis software for easy transferring of stored results or real-time viewing
  • Control sample mixing directly from the meter without a separate stir plate when using with the Orion Star stirrer probe (cat. no. 096019, sold separately)
  • Increase your productivity - with two Orion stirrer probe ports, add stirrers and modules to analyze two separate samples at the same time
  • 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 through the included universal power adapter
  • IP54-rated housing handles splashes and cleans up easily
  • 3 year meter replacement warranty
