 The figure above shows the case when the pH 10 standard solution is 25.0 ºC
When the sample is known as acidic or alkaline, some of the calibration can be skipped
Acidity: Perform calibration on pH7 and pH 4 and skip on pH10
Alkalinity: Perform calibration on pH 7 and 10 and skip on pH 4
Relation between pH value and temperature
When performing calibration, set the pH value according to the temperature of the standard solution as follows;
Standard solution Name of solution Temp. pH value Temp. pH value
pH 4 Phthalate solution
0 ºC 4.00 30ºC 4.02
5 ºC 4.00 35ºC 4.02
10ºC 4.00 40ºC 4.04
