Thermo Orion Star A325 pH/Conductivity Portable 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 points.
• Advanced features such as stability and averaging options available.
• 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. Fix calibration errors without a complete recalibration with calibration editing.
• Selectable cell constant allows for use with 2- or 4-cell conductivity cells.
• Selectable reading reference temperatures of 5, 10, 15, 20, 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.
• Waterproof. IP67-rated housing.
• Multilingual interface supports English, Spanish, French, Italian, German and Chinese.
• Log function: manual, ready (include 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 and USB.
• Power: 4 x AA batteries (included) provide over 800 hours of operation, or use the AC adapter (sold separately) for 100-240V.
• Warranty: 3 year meter replacement.

Specifications:
