Its large-area diaphragm sits close to the glass sensing membrane, creating a short, consistent path between the reference junction and measuring element. This arrangement supports a fast response and helps reduce the effect of changes in sample flow on measurement stability.\u003c\/p\u003e\n\u003cp\u003eControlled electrolyte diffusion limits the amount of electrolyte entering the sample, making the electrode suitable for pure-water monitoring.
