pH 300 meter calibration
The pH 300 meter is capable of up to 5-point pH calibration to ensure accuracy across the entire pH
range of the meter. Select from the following buffer options:
•
USA buffers --- pH 1.68; 4.01, 7.00, 10.01, and 12.45.
The meter automatically recognizes and calibrates to these standard buffer values, which makes pH
calibration faster and easier.
pH 310 meter calibration
The pH 310 meter features three separate internationally-recognized buffer standards. Select the
buffer standard you require in SETUP mode Program 4.0 (see pages 27 & 34 for more information).
The pH 310 meter is capable of up to 6-point pH calibration, depending on the buffer standard
selection. Select from the following buffer options:
•
USA buffers --- pH 1.68, 4.01, 7.00, 10.01, and 12.45.
•
NIST buffers --- pH 1.68, 4.01, 6.86, 9.18, and 12.45.
•
DIN buffers --- pH 1.09, 3.06, 4.65, 6.79, 9.23, and 12.75.
The meter automatically recognizes and calibrates to these standard buffer values, which makes pH
calibration faster and easier.
