Basic characteristics of PH pure water electrode
1. Filled with high molecular polymer, the reference junction potential is very stable.
2. The diffusion potential is very stable. Because the large-area diaphragm is distributed around the glass bubble, the distance between the reference diaphragm and the glass bubble is constant and close, and the ions diffused by the diaphragm quickly form a complete measurement with the glass electrode. The loop responds quickly, so that the diffusion potential is not easily affected by the external flow rate and so on, so it is very stable.
3. Since the diaphragm is filled with high molecular polymer, the electrolyte outflow is small and stable, and will not pollute the pure water measured.
Therefore, the above characteristics of the composite electrode make it very suitable for measuring the PH value of high-purity water!
Measurement of pure water and high-purity water in pharmaceutical, chlor-alkali chemicals, pigments and dyes, pulp and paper, intermediates, fertilizers, starch, environmental protection and other industries
