Use Thermo Scientific™ Orion Star™ A325 pH/Conductivity Portable Multiparameter to retrieve accurate results from any location, which is a sturdy and reliable choice for every sample.

Measurement Mode(s):Conductivity, mV, pH, Resistivity, Salinity, TDS, Temperature
Measurement Resolution:0.1 pH, 0.01 pH, 0.001 pH, 0.1 mV, 0.1 °C, 0.001 µS minimum, 2 ohms-cm, 4 significant digit TDS
Conductivity Measuring Range:0.001 µS/cm to 3000 mS/cm

The large backlit graphic LCD display can quickly and easily obtain the information you need. The display can display a single pH / mV / RmV or conductivity / TDS / salinity / resistivity results with temperature, or display all results at once
Other useful information includes electrode status, time, date, sample ID, user ID and calibration point
Advanced features such as stability and averaging provide additional options to achieve laboratory accuracy wherever you need
Common language screen prompts and softkeys will be updated for easy selection
Multilingual interface, supports English, Spanish, French, Italian, German and Chinese
Thermo Scientific™AUTO-READ™ locks the stable reading on the screen. When the reading is stable, the ready indicator alarm will be issued, and the regular reading will collect data within a specific time interval.
Up to five-point pH calibration automatically recognizes USA/NIST™ and DIN buffers
Calibration editing allows users to fix pH calibration errors without having to completely recalibrate
Optional battery constant allows use with 2 or 4 cell conductivity cells
Selectable reading reference temperature with linear, non-linear, nLFu or EP curve options is 5°, 10°, 15°, 20° or 25°C, providing higher accuracy of conductivity readings
Users can choose actual salinity or natural seawater curve to read salinity
Provide linear or ISO/EN 27888 curves for TDS
USB and RS232 ports and free data analysis software make it easy for users to transfer data and keep the instrument software up to date
