· Adoption of the most advanced Teflon diaphragm with large ring section to make the electrode with stable liquid juntion;

· Strong anti-interference ability; It is not easy to be polluted and blocked; Long life;

· The reference system is filled with the high polymer; Convenient use; It is unnecessary to refilling electrolyte.

· Sensitive response of electrode (the measured value 95%can be reached up in several seconds);

· PH range: 0~14pH the temperature range: 0~110o C;

· Pressure resistance of the electrode: 0.6MP and the zero potential E0=7pH
· Outer tube material: Glass or PPS plastic

· The external dimension of the electrode is φ12x120, 225 or other dimensions.
