pH Meter -pH Scale -pH Testers

The pH measurement is a relative measurement, it only indicates the pH difference between the standard solution and the unknown solution. In the actual measurement, it needs to be calibrated regularly with the standard buffer solution. Therefore, in order to achieve the same value, a pH scale must be established. The pH scale range is set to 0-14 pH. The pH scale value is determined by the pHs of the reference buffer solution.

Therefore, the meaning of the pH scale can be expressed as follows: According to the pH definition, several pH buffer solutions are selected within the pH range of 0-14 as the fixed point of the pH scale, and their pHs are determined by the most accurate method that can be achieved by the contemporary technology. value. There are two kinds of pH scales in the world, namely, multiple reference pH scales and single reference pH scales, and China adopts multiple reference pHs scales.

The company specializes in producing all kinds of ph meter, welcome to consult procurement.
