Product Options


The Thermo Scientific Orion™ VERSA STAR™ Conductivity Benchtop Meter measures conductivity, TDS, salinity or resistivity with temperature measurements. All information is displayed on its display showing readings, connections, time, date, sample ID, user ID and calibration. User friendly language with screen prompts makes updates and selection an easy process. Up to 2000 data points can be stored all with time and date stamps in the non-volatile memory. Data analysis software is used to provide transfer of stored data and also for displaying readings in real time.

There are many handy features of the VERSA STAR™ and these are:

  • Five modules to customize the four channels as required
  • Multilanguage interface that supports English, Spanish, French, Italian, German and Chinese
  • Two USB and RS232 ports for the ease of data transfer and updating meter software
  • Direct control for two Orion Star stirrer probes (096019, sold separately) for mixing samples without a stir plate
  • Electrode arm and newly designed probe holder makes it easier to maintain and place probes into samples
  • Universal power adapter that works with almost every AC power source
  • IP54-rated housing handles splashes

VERSA STAR Conductivity Module, VSTAR-CND:

  • Selectable conductivity reference temperatures of 5, 10, 15, 20, or 25°C with linear, non-linear nLFn, non-linear nLFu and EP curve options
  • Choice of practical salinity or natural sea water curves for salinity
