VERSA STAR PRO™ Benchtop pH Meters

Not yet rated

Get high accuracy, premium performance and ultimate flexibility with the Thermo Scientific™ Orion™ Versa Star PRO Benchtop Meter with pH Module. Meet your most challenging applications for pH, mV, ORP and temperature. Easily view measurements on the stunning color display and customize the four meter channels with interchangeable modules. Perform up to a six point pH calibration, 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. Use the included electrode stand to easily place sensors in samples.

  • 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
  • Easily access, update and switch your preferred measurement settings, using ten password-protected methods per channel
  • 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 2,000 measurement sets with optional electrode ID, sample ID and user ID
  • 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 meter memory preserves data and settings, even in the event of power loss
  • Orion Star Com software facilitates data transfers to a computer via USB or RS232 connections
  • IP54-rated housing resists dust and splashes and can be wall-mounted if table space is limited
  • Meters include CE, TUV 3-in-1 and FCC Class A certifications and 3-year replacement warranty

Includes Orion Versa Star PRO pH Measurement Module:

  • Measure pH, 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 with choice to manually enter custom buffer values
  • Calibration editing option allows individual points to be fixed without a full recalibration
  • Customize measurements to show calibration history and pH electrode condition or simplify to show an extra large pH reading
