Thermo Scientific Orion ROSS® pH Electrodes
The standard for accurate, reproducible pH measurements
ROSS Specifi cations :
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
Mercury free, TRIS, protein and
sulfi de compatible
Temperature Response
The ROSS electrode continues to show fast
reproducibility and accuracy after many,
dramatic temperature changes.
