1. Adopting the circular large section Teflon diaphragm imported from Germany, it provides stable liquid contact potential and low resistance characteristics, preventing blockage and pollution.

2. Introducing German reference process technology, unique solution formula, resistant to strong acids, strong alkalis, and high temperatures, without the need for electrolyte supplementation. Electrode response is fast, stable, and has a long service life. Built in salt bridge can better prevent electrodes from being subjected to S^2-， CN^-Plasma erosion.

3. The electrode is mainly suitable for pH measurement of general pure water, industrial water, and sewage.

4. PH range 0-14, temperature range 0-80 ℃, pressure range ≤ 0.6Mpa, zero potential PH=7.00

5. The external dimensions of the electrode are Ø 12 × 120, 150, 225 or other sizes.

Two composite electrodes:Adopting the internationally recognized PG13.5 thread installation seal, the outer tube material is glass, which can be directly matched with various pH meters at home and abroadTriple composite electrode:Adopting the internationally recognized PG13.5 thread installation seal, the temperature compensation resistor adopts Pt100, Pt1000 or thermistor (to be specified when ordering), and the outer tube material is glass, which can be directly matched with various pH meters at home and abroad.
