· 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

· The outer tube material: Glass or PPS plastic
· The external dimension of the electrode is ¦Õ12x120, 225 or other dimensions.
