Thermo Scientific Orion Ross Ultra Combination pH Electrodes

The Orion ROSS pH electrode, which is recognized as the best pH electrode in the world for difficult samples, is now even better. The Orion ROSS Ultra has twice the warranty and greater stability than its predecessor. It uses uses a unique reference system developed by Thermo Scientific that offers longer life, greater stability, and fast results, regardless of sample composition or temperature.

Extended warranty to 24 months when typical pH electrode warranties are 3 to 12 months
Measurements are more stable and accurate
Unparalleled pH response to temperature changes
Designed for the most difficult samples
Slope: 92-102% of theoretical Nernst slope
Isopotential point: pH 7
Accuracy of measuring a pH 6.86 buffer after standardization at 25°C: Accurate
within 0.03 pH for buffer at any temperature between 0-100°C using automatic temperature compensation.
Speed of response in 6.86 buffer going from 25° C to 75°C: Response stable to 0.01 pH within 30 seconds.
Speed of response between 6.86 and 4.01 buffers at 25°C: Response stable to 0.002 pH within 15 seconds.
Reference filling solution: 3M KCl (supplied with electrode), Cat. No. 810007.
