Thermo Orion® Star A215 pH/Conductivity Benchtop Meters

  • Large, backlit graphic LCD display shows individual pH/mV/RmV or conductivity/TDS/salinity/resistivity results with temperature, or all results at once.
  • Additional 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.
  • AUTO-READ™ locks in the stable reading, ready indicator alerts when readings are stable and timed reading gathers data in specific time intervals.
  • Non-volatile memory holds up to 2000 data points with time and date stamp.
  • Up to 5-point pH calibration with automatic recognition for USA/NIST and DIN buffers and calibration editing to fix errors without a complete recalibration.
  • Up to 5-point conductivity calibration with calibration editing.
  • Selectable cell constant allows for use with 2- or 4-cell conductivity cells.
  • For accurate conductivity results, selectable reading reference temperatures of 5, 10, 15, 20 or 25ºC 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.
  • IP54-rated housing handles splashes and is wall mountable.
  • Multilingual interface supports English, Spanish, French, Italian, German and Chinese.
  • Log function: manual, ready (includes AUTO-READ™), timed. Log edit: delete individual points, group of points or all.
  • Inputs: (pH electrode) BNC, reference pin; (Conductivity with temperature probe or ATC probe) 8-pin mini-DIN.
  • Output: RS232 or USB.
  • Power: 100-240V AC adapter (included) or 4xAA batteries (sold separately) for up to 800 hours of use. CE marked.
  • Warranty: 3 year meter replacement.

  • pH range: -2.000 to 20.000 ±0.002.
  • mV/RmV range: ±2000.0mV ±0.2mV or ±0.05% of reading, whichever is greater. EH ORP mode.
  • Conductivity range: 0.001µS to 3000mS. Accuracy: 0.5% of reading ± 1 digit. Compatible cell constants: 0.001 to 199.9.
  • Resistivity range: 2ê to 100Mê. Accuracy: 0.5% of reading ± 1 digit.
  • Salinity range: 0.01 to 80.0ppt NaCl equivalent; 0.01 to 42ppt practical salinity. Accuracy: ±0.1.
  • TDS range: 1 to 200ppt. Accuracy: 0.5% of reading ± 1 digit. TDS factor range: Linear 0.01 to 10.00, default 0.49.
  • Temperature range: -5.0 to 105.0ºC (23 to 221ºF) ±0.1º. Offset calibration: 1 point.
