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:  
• 
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. 
 
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:  
• 
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. 
• 
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.
