Looking for the top-of-the-line, best meter you can find? Looking for something for everything and meeting all those testing needs? Whether it's one sample that needs a variety of testing or a variety of samples needing one test, the Orion VERSA STAR 90 and 91 advanced multiparameter meters are ready for the job. These meters come fully-loaded and ready to take on multiple measurements.

  • Customize the display to show only the information you need
  • 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
  • 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
