Orion Star™ A325 portable pH/Conductivity Meter
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 include electrode status, time, date, sample ID, user ID and calibration points. Advanced features such as stability and averaging options provide additional options allowing for laboratory accuracy everywhere you need it.
Orion STAR* A325 portable pH/Conductivity Meter Kit includes meter, ROSS Ultra triode pH/ATC, DuraProbe 3m cond cell, cond std., rinse, buffer pouches, ROSS solution.
