Product Options


The Orion™ VERSA STAR™ DO Benchtop Meter is an advanced electrochemistry meter which has many attractive features such as including a dissolved oxygen/temperature module and providing four channels that can be customized with any of the five available modules. All readings, connections, time, date, sample ID, user ID and calibration information are displayed on the large screen. Simple prompts make using this meter a very simple process. The large 2000 data point memory stores all readings time and date stamped, the transfer of this data and meter software updates is easy using the two USB ports and RS232 ports.

Other features which make this meter the ideal option are:

  • Meter allows direct control of two Orion Star stirrer probes for mixing samples without a stir plate
  • Electrode arm and newly designed probe holder make it easier to maintain and place probes into samples
  • IP54-rated housing withstands splashes
  • Universal power adapter works with almost every AC power source

VERSA STAR Dissolved Oxygen/RDO Module, VSTAR-RD:

  • Dissolved oxygen as percent saturation or concentration with temperature measurements
  • Flexibility to use Orion polarographic or RDO optical dissolved oxygen probes with automatic meter recognition of the probe type
  • Calibration options for water-saturated air, air-saturated water, custom value using a Winkler titration or zero point
  • Automatic compensation for temperature and barometric pressure with option for automatic or manual salinity correction
