Thermo Orion Versa Star Multiparameter Meter VSTAR91

- Benchtop advanced meter with four modules that display pH, ORP, Ion Selective Electrode (ISE), Conductivity (Conductivity, TDS, Salinity Resistivity), RDO/DO (DO, BOD, DOUR, SOUR), and temperature on customizable channels on the large color LCD display
- pH/ISE module provides all the features of pH and advanced ISE testing, Conductivity module has selectable reading reference temperatures with linear, non-linear, nLFu, or EP curve options
- Accepts Orion polarographic and RDO optical/luminescence-based probes, and calibration is possible using water-saturated air, air-saturated water, Winkler titration, or zero point
- Each channel can store 10 methods in memory for differentiating between tests and/or users
- Data logging function can be set to timed, continuous update, manual, and auto-read that locks readings on the screen, with alert signals when reading is stable
- Includes Versa Star meter, 1 integral electrode arms with probe holder, 2 pH/ISE module, 1 Conductivity module, 1 RDO/DO module and universal power adapter (order electrodes and calibration solutions separately)
