Multiparameter benchtop meter model DUAL STAR

ORION DUAL STAR ion concentration analyzer, measures simultaneously with different selective electrodes.

Suitable for high-throughput ion and pH analysis in the laboratory.

• Measuring capacity in the 2 channels of pH, ORP and ISE.
• Simultaneous measurement of the 2 channels for different ionic species.
• Automatic sampler for 28 samples (optional)
• Known incremental methods of addition and subtraction.
• Allows to store 10 measurement methods per channel.
• Stores calibration results and graphs.
• Storage of 1000 data with date and time

**Replaced by the new model PSTAR2175 of the new Pro Star series.
