About Conductivity
Conductivity:The conductivity of water is usually used to indicate the purity of water. If the conductivity is high, it means that the content of conductive minerals in water is very high, and the purity of water is very low. If the conductivity is very low, it indicates the minerals that can be ionized in water. Rarely, the purity of water is relatively high. For example, the conductivity of high-purity water is EC=0.1.0us/cm; the conductivity of ordinary drinking water is 1~10 us/c.
About us
In the course of ten years of development, we have been constantly working hard in this field, and constantly improving product functions, testing accuracy, dedicating to environmental water quality monitoring and rapid monitoring of product development. The products developed and produced mainly include COD, ammonia nitrogen, total phosphorus, total ammonia integrated machine, miniature COD reactor, water quality monitoring electrode, digital refractometer, etc. Most of the company’s products have obtained CE certification; widely used in domestic environmental protection bureaus, industrial enterprises, university research institutes, food manufacturing enterprises; especially electrochemical testing products have been sold at domestic and foreign.
We sincerely welcome domestic and foreign merchants to achieve win-win cooperation, common development and create brilliant!
