The Thermo Scientific Orion Star A212 Conductivity Benchtop Meter is the ideal choice for any lab. Get the information you need quickly and easily from the large, backlit graphic LCD display. Informative display shows conductivity/ TDS/salinity/resistivity and temperature along with time, date, sample ID, user ID and calibration information. For advanced users, features such as stability and averaging choices provide additional options.
  • Anyone can use this meter with its plain language screen prompts, soft keys that update for easy selection and a multilanguage interface that supports English, Spanish, French, Italian, German and Chinese
  • Don't miss a reading – AUTO-READ™ locks in the stable reading on your screen, ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals
  • Selectable cell constant allows for use with 2- or 4-cell conductivity cells
  • For accurate results, selectable reading reference temperatures of 5, 10, 15, 20 or 25™C with linear, non-linear, nLFu or EP curve options
  • Choice of practical salinity or natural sea water curves for salinity readings
  • Linear or ISO/EN 27888 curves for TDS
  • Non-volatile memory holds up to 2000 data points with time and date stamp
  • Easily transfer data and keep meter software up-to-date with the USB and RS232 ports and complimentary data analysis software
  • Mix samples without a stir plate with direct control of the Orion Star stirrer probe (096019, sold separately)
