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.
Get the information you need quickly and easily from the large, backlit graphic LCD display, which 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.
Plain language screen prompts and soft keys that update for easy selection
Multilanguage interface that supports English, Spanish, French, Italian, German and Chinese
Thermo Scientific 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
