High-Precision Benchtop Systems for Conductivity, TDS, Salinity, and Resistivity Analysis
The Thermo Scientific™ Orion™ Versa Star Pro™ Conductivity Benchtop Meters deliver unmatched flexibility, accuracy, and functionality for laboratories performing complex electrochemical measurements. Designed to measure conductivity, total dissolved solids (TDS), salinity, resistivity, and temperature, these benchtop systems support advanced calibration, data management, and modular customization to meet evolving lab requirements.
Available in three versions, each system includes the Versa Star Pro meter with conductivity module (VSTAR-CND). The VSTAR22 includes a general-purpose 4-cell conductivity sensor, the VSTAR23 includes a low-conductivity pure water cell with flow cell, while the VSTAR20 is supplied without a sensor for use with custom configurations.
