· 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 external dimension of the electrode is ¦Õ12x120, 225 or other dimensions.

· The electrode has the fixed cable and the length of the cable can be adjusted according to the requirements of the users

· The pH value of skin, paper and fruit and so on can be measured;

· The pH value of the micro test sample can be measured
