The new 2-Star pH Benchtop meter offers ease-of-use with simple three-button operation and is value priced for general purpose pH measurements in the laboratory. Specifically designed for environmental, industrial and educational applications, the Orion 2-Star is a significant upgrade from Thermo Scientific’s Orion 410A+/420A+ meters.

The new meter provides a simple, intuitive user interface with a pullout quick start guide feature while offering up to three-point calibration and auto calibration compatible with NIST and DIN buffers.  A 50 point data log enables time, stability or manual readings with time/date stamp.

The Orion 2-Star benchtop pH meter is value priced for general purpose pH measurements in the laboratory. The meter offers quick reliable pH and temperature measurements with a variety of probe choices to suit specific industrial and educational applications.
