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. Since the large-area diaphragm is distributed around the glass membrane bubble, the distance from the reference membrane to the glass membrane bubble is constant and close, and the ions diffused from the membrane 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, etc., so it is very stable.
3. Since the diaphragm is filled with high molecular polymer, the outflow of electrolyte is small and stable, and will not pollute the pure water to be measured.
Therefore, the above characteristics of the composite electrode make it very suitable for measuring the pH value of high-purity water!
