Multi-parameter meter (pH/ISE/conductivity/oxygen), bench top, Orion™ Versa Star Pro™
Electrochemistry Meters pH and Multi-Parameter Meters
These bench top meters with pH/ISE, conductivity and Dissolved Oxygen/RDO modules meet the most challenging applications for pH, ion concentration, conductivity, dissolved oxygen and temperature. The meters offer interchangeable measurement modules that allow multiple users to customise four separate channels to meet their specific requirements.

  • Colour display with adjustable text sizes; numeric keypad; onscreen measurement stability indicator
  • Auto-Read to hold a stable reading; ten password-protected methods per channel
  • Audible alarms automatically notify
