Thermo Scientific Orion Versa Star Pro 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 Pro 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.   

Onscreen measurement stability indicator lets you know exactly when your measurements are ready    

Selectable read modes include Auto-Read to hold a stable reading, Continuous to show changing readings, Timed to log data at specific intervals and Single-Shot to hold a reading after a specific wait time is reached   

Audible alarms automatically notify you when a set offset value, high/low limit value, and calibration time interval are reached   

Uniformly mix solutions using up to two meter-controlled stirrer probes that are easy to position and can be quickly rinsed between samples   

Data log collects and date/time stamps up to 2000 measurement sets with optional electrode ID, sample ID and account ID    

Calibration log stores 30 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 meter memory preserves data and settings, even in the event of power loss    

Meter facilitates data transfers to a computer via USB or RS232 connections    

Meters include CE, TUV 3-in-1 and FCC Class A certifications and 3-year replacement warranty   
   

Includes Orion Versa Star pH/ISE Measurement Module:   

Measure pH, ion concentration, mV, relative mV or ORP with temperature   

Perform up to a six point pH calibration using automatic buffer recognition of NIST, DIN or user-defined buffer groups    

Perform up to a six point ISE calibration with selectable units of ppm, M, mg/L, %, ppb or none   
   

Includes Orion Versa Star Conductivity Measurement Module:   

Measure conductivity, TDS, salinity or resistivity with temperature   

Perform up to a six point conductivity calibration   

Use linear, non-linear, EP (USP) or off conductivity temperature compensation with 5, 10, 15, 20 or 25°C reference temperatures   
   

Includes Orion Versa Star RDO/DO Measurement Module:   

Measure dissolved oxygen in percent saturation or mg/L with temperature using Orion RDO optical DO probes or Orion polarographic DO probes    

Calibrate DO using water-saturated air, air-saturated water, custom value (Winkler titration) and zero point options   

Automatically compensate DO readings using ATC temperature, manual salinity input and built-in barometer for barometric pressure
