- Electrode and RTD sensor must be used in a perpendicular position.
- For the standardization and calibration of pH meter, always use freshly prepared buffer solution and measure at 250C.
- While calibrating the pH meter, Use buffer in near the expected value from the sample, this will reduce the span error
- The electrode should be washed between the sample measurements with deionized or distilled water.
- To remove excess water, never rub the electrode bulb; just dry the tip end of the electrode with a clean tissue paper.
- For the rapid response, stir electrodes in the sample or buffer.
- Reactivate or change the electrode with a new one, if variation for pH 4.00 or pH 9.20 before calibration is greater than 0.3 pH.
