Page 19: Preparation Of The Ph Electrode
- 13 - 7. Preparation of the pH electrode The electrode should be prepared to work according to the manufacturer’s instructions. If the instructions weren’t given please follow the steps: - new electrode should be put into saturated KCl solution for about 5 hours: - before starting measurements, protecting rings (if used in this kind of electrode) should be removed. -
Page 20: Calibration
2 buffer solutions: 4.00 and 7.00 pH is recommended, in case of alkali measurements calibration in 7.00 and 10.00 pH buffers is advisable. In CP-511 the slope of the electrode is approximated in segments between the calibration points. Starting the calibration process irreversibly erases the calibration data stored in the memory. -

- 19 - pH measurement Before starting measurement, prepare the meter (chapter 6) and the pH electrode (chapter 7) to work. Good condition of the electrode is the most important condition for accurate measurements. 10.1. Measurement with automatic temperature compensation During measurements with automatic temperature compensation the meter cooperates with the temperature probe and measures the temperature of the solution simultaneously with pH. -

Page 27: Notices About The Temperature Compensation And Interpretation Of The Measurement Results
- 21 - Notices about the temperature compensation and interpretation of the measurement results The CP-511 pH meter has an automatic temperature compensation, which enables eliminating errors resulting from affecting electrode characteristics by temperature changes. To explain the role of the temperature compensation it is important to remind that pH meter is an mV meter which displays redox counted to pH. - Page 28 Slight differences of the results are connected with the accuracy of the meter. The accuracy of CP-511 is ±0,01 pH, ±1 digit, what practically means that in extreme conditions results of two measurements of the same solution may differ in ±0,05 pH. This is an acceptable error, because one result has error equal –...
