Add pH, ion concentration, mV, ORP and temperature measurement capabilities to your Thermo Scientific™ Orion™ Versa Star meter using the Thermo Scientific™ Orion™ Versa Star pH / ISE Measurement Module. Each Orion™ Versa Star meter has four channels that can be customized with interchangeable measurement modules. The Versa Star pH/ISE module offers up to six point pH and ISE calibrations and advanced ISE features including incremental techniques (single and double known addition and subtraction, analate addition and subtraction), low range stability and electrode ID with calibration verification.

Select from five Thermo Scientific Orion Versa Star measurement modules to customize the measurement capabilities of your Orion Versa Star meter. Measurement modules are interchangeable and can be added or removed from each Versa Star meter’s four channels at any time.

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 with choice to manually enter custom buffer values
  • Perform up to a six point ISE (Ion Selective Electrode) calibration with selectable units of ppm, M, mg/L, %, ppb or none
  • Incremental techniques include single known addition, double known addition, single known subtraction, double known subtraction, analate addition and analate subtraction
  • Advanced ISE features include non-linear selectable auto-blank, low range stability and electrode ID with calibration verification
  • Customize measurements to show calibration history and pH electrode condition or simplify to show an extra large pH or ion concentration reading
  • Module offers a 3-year replacement warranty
