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.
