Versatile, High-Performance Laboratory Measurement System

Thermo Scientific Orion Versa Star benchtop meters are designed to meet your most challenging application with ease. Delivering rich functionality and features, you can optimally configure your meter system to meet changing requirements. The Orion Versa Star benchtop meters offer interchangeable measurement modules that allow multiple users to customize four separate channels to meet their specific requirements.

Easily view your measurements on a stunning color display with adjustable text sizes. Take the guesswork out of meter calibration and setup with onscreen instructions available in a variety of local
languages. Enjoy quick and simple data entry using the numeric keypad.

Collect, store, and export your critical data:

  • „„Data log collects up to 2000 data points with time and date stamp; enhance data tracking using electrode ID, sample ID and user ID options
  • „„Calibration log stores ten most recent calibrations per parameter with viewable graph for multipoint pH and ISE calibrations
  • „„Ensure measurement integrity by viewing the active calibration log while taking readings
  • „„Non-volatile memory preserves data and settings, even in the event of power loss
  • „„Free Orion Star Com software facilitates data transfers to a computer via USB or RS232 connections

Premium ease-of-use features:

  • „Onscreen measurement stability indicator lets you know exactly when your measurements are ready and is adjustable using custom stability and averaging settings
  • „„Audible alarms automatically notify you when a set offset value, high/low limit value, and calibration time interval are reached
  • „„Easily access, update and switch your preferred measurement settings, using ten password-protected methods per channel
  • „„Uniformly mix solutions using meter-controlled stirrer probes that are easy to position and can be quickly rinsed between samples
