8.5.2 Calibrating pH Electrodes Using Automatic Buffer recognition
Analyzer stores information on multiple buffers
The UDA2182 Universal Dual Analyzer contains (in its permanent memory) information
on several commonly used buffer solution standards in three groups, including the pH
versus temperature characteristics of each.
By command, the instrument will automatically select one of these buffers in the selected
group and use its values in the calibration process. Automatic checks are included to
ensure that reasonable and correct values are entered.
The procedure for using the automatic buffer recognition feature in an actual calibration is
provided in Table 8-2.
The standard pH Buffer values are listed in Table 8-1.
