Basic Principle of pH Electrode 1.The polymer filling makes the reference junction potential very stable. 2. The diffusion potential is very stable; large-area diaphragm surrounds the glass diaphragm bubbles, so that the distance from the reference diaphragm to the glass diaphragm is near and constant; the ions diffused from diaphragm and the glass electrode quickly form a complete measurement circuit to respond quickly, so that the diffusion potential is not easy to be affected by the outside flow rate and is thus very stable! 3. As the diaphragm adopts the polymer filling and there is small and stable amount of overflowing electrolyte, it shall not pollute the measured pure water. Therefore, the above-mentioned features of the composite electrode make it ideal for measuring PH value of high-purity water! Technical Indexes

Features of pH Electrode ● It adopts the world-class solid dielectric and a large area of PCE liquid for junction, difficult to block and Convenient maintenance. ● Long-distance reference diffusion channel greatly extends the service life of electrodes in the harsh environment. ● It adopts PPS/PC casing and the upper and lower 3/4NPT pipe thread, so it is easy for installation and there is no need of the jacket, thus saving the installation cost. ● The electrode adopts the high-quality low-noise cable, which makes the signal output length more than 40 meters free of interference. ● There is no need for additional dielectric and there is a little amount of maintenance. ● High measurement accuracy, fast echoing and good repeatability. ● Reference electrode with silver ions Ag/AgCL. ● Proper operation shall make service life longer. ● It can be installed in the reaction tank or pipe laterally or vertically. ● The electrode can be replaced by a similar electrode made by any other country. Why monitor the pH of water? pH measurement is a key step in many water testing and purification processes: ●A change in the pH level of water can alter the behavior of chemicals in the water. ●pH affects product quality and consumer safety. Changes in pH can alter flavor, color, shelf-life, product stability and acidity. ●Inadequate pH of tap water can cause corrosion in the distribution system and can allow harmful heavy metals to leach out. ●Managing industrial water pH environments helps prevent corrosion and damage to equipment. ●In natural environments, pH can affect plants and animals.
