4.2.1 pH 11 meter calibration
The pH 11 meter is capable of up to 5-point pH calibration to ensure accuracy across
the entire pH range of the meter. You can select from the following buffer options:
x
USA buffers --- pH 1.68, 4.01, 7.00, 10.01, and 12.45.
x
NIST buffers --- pH 1.68, 4.01, 6.86, 9.18, and 12.45.
4.2.2 pH 110 meter calibration
The pH 110 meter features four separate internationally recognised buffer standards.
Select the buffer standard you require in section 9.2.2 - P1.2: Select Calibration
Buffer Options on page 35.
This meter is capable of up to 6-point pH calibration, depending on the buffer
standard selection. You can select from the following buffer options:
x
USA buffers --- pH 1.68, 4.01, 7.00, 10.01, and 12.45.
x
NIST buffers --- pH 1.68, 4.01, 6.86, 9.18, and 12.45.
x
DIN buffers --- pH 1.09, 3.06, 4.65, 6.79, 9.23, and 12.75.
x
PWB (Low Ionic): pH 4.10 and 6.97
The meter automatically recognises and calibrates to these standard buffer values,
which makes pH calibration faster and easier.
