Page 22: Calibration And Adjustment
The service life of a pH glass electrode is limited. One of the reasons for this is the deterioration and aging of the pH-sensitive membrane glass. This aging causes the gel-like layer to change and become thicker over time. Symptoms of aging include: • Higher membrane resistance • Slow response • Decrease in the slope Endress+Hauser... - Page 23 Calibrating with buffers with pH 7.0 and 4.0 is recommended for most applications. You use calibration buffers to perform two-point calibration. The quality buffers supplied by Endress+Hauser are certified and measured in an accredited laboratory. The accreditation (DAR registration number "DKD-K-52701") confirms that the actual values and the maximum deviations are correct and traceable.
