Description

Get high accuracy and premium performance everywhere you need it with the Thermo Scientific™ Orion™ Star A325 pH and Conductivity Portable Meter, designed for a wide range of pH, mV, ORP, conductivity, total dissolved solids (TDS), salinity, resistivity and temperature testing and field applications. Evaluate samples in the most demanding locations using this waterproof meter with IP67-rated housing. Use the two channels to measure pH and conductivity simultaneously or view each channel separately. Log up to 5000 data point sets with time / date stamp and transfer logs to a printer or computer.

The Thermo Scientific Orion Star A325 pH/ Conductivity Portable Meter is the top choice for advanced measurements on location. 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 points. Advanced features such as stability and averaging provide additional options allowing for laboratory accuracy everywhere you need it.
  • 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
  • Up to five point pH calibration with automatic recognition for USA/NIST™ and DIN buffers
  • Fix pH calibration errors without a complete recalibration with calibration editing
  • Selectable cell constant allows for use with 2- or 4-cell conductivity cells
  • For advanced accuracy in conductivity readings, selectable reading reference temperatures of 5°, 10°, 15°, 20° or 25°C with linear, nonlinear, 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
  • Nonvolatile memory holds up to 5000 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
  • Four AA batteries (included) provide over 800 hours of operation or purchase the universal power adapter (sold separately) to use AC power
  • Perfectly portable, waterproof and protected to take anywhere with a IP67-rated housing
  • Three year meter replacement warranty
