8.5.4Sample Method of Calibrating pH Electrodes

Recommended where pH is stable, or for high-purity water applications

This method is recommended only where the pH is stable and changes very slowly. It is also recommended for high-purity water measurement applications. Special instructions for high-purity water applications are provided below.

Materials

To use the sample method, follow the instructions in Table 8-4. Materials required are:

•A clean beaker for collecting the sample.

•A calibrated portable instrument for measuring pH of the sample.

•Distilled or de-ionized water to rinse the electrode.

Procedure

Make sure you have selected “PV Type –pH Glass, pH Durafet, or pH HPW” in the Inputs configuration - Table 6-5.

Refer to Section 6.4.1 – General Rules for Editing.
