The Thermo Scientific Orion Star A215 pH/Conductivity Benchtop Meter is the ideal choice for any pharmacology lab. Get the information you need quickly and easily from the large, backlit graphic LCD display. Informative display shows individual pH/mV/RmV or conductivity/TDS/salinity/resistivity results with temperature, or all results at once. Additional helpful information includes electrode status, time, date, sample ID, user ID and calibration. For advanced users, features such as stability and averaging choices provide additional options.

  • Anyone can use this meter with its plain language screen prompts, function 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
  • Up to five point pH calibration with automatic recognition for USAIST and DIN buffers and calibration editing to fix errors without a complete recalibration
  • 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 USP/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
  • Stores up to 10 methods per channel allow for customized procedures to differentiate between tests and/or users
  • 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)
  • Included electrode arm and newly-designed probe holder make it easier to maintain and place probes into samples
  • Works with almost every AC power source with the included universal power adapter, or use four AA batteries (sold separately) to run the meter on DC power
  • IP54-rated housing handles splashes and is wall-mountable if table space is a problem
  • 3 year meter replacement warranty
  • Includes Electrode arm and universal power adapter
