Thermo Scientific Orion ROSS Electrodes
Reliable and accurate pH measurement is highly dependent upon both the design and manufactured quality of the pH electrode.  Of all the electrode features that influence the performance of pH probes, the reference element and the composition of the sensing glass are the most critical.

The unique reference chemistry of Orion ROSS electrodes is designed to deliver outstanding accuracy and trouble-free measurements.

Compared to conventional electrodes, the proven ROSS reference system exhibits stability in measurements, faster response, greater accuracy and precision when measuring samples that vary in temperature.

• Stabilization to 0.01 pH units in less than 30 seconds when checking samples using pH 6.86 buffer that vary in temperature by 50ºC (25–75 ºC)
• Measurement accuracy to ±0.03 pH units and precision to ±0.01 pH units using the same buffer and automatic temperature compensation
