Universal Disinfectant Controller In many water treatment occasions, it is necessary to add disinfectants to the water to eliminate germs and microorganisms in the water. Such as water plants, swimming pools, industrial production processes, etc. After disinfection, there will be some residual substances in the water, such as residual chlorine, chlorine dioxide, ozone, etc. Daruifuno's universal disinfectant controller can be connected with disinfectant sensors such as online residual Chlorine Sensor , online Chlorine Dioxide Sensor, online Total Chlorine Sensor , online Hydrogen Peroxide Sensor, online Ozone Sensor , water bromine sensor, Peracetic Acid Sensor and other disinfectant sensors of film coating method to realize real-time continuous monitoring of water quality. The disinfectant controller has 2 relays by default, 1 channel of 4-20mA current and RS485 digital interface, and supports Modbus communication protocol. We are a manufacturer of disinfectant controllers, we provide many different kinds of water quality analysis instruments. If you are interested in our products, please contact us.

The neodymium magnet is the third generation permanent magnet which have the most extensive application in the modern industries. Neodymium magnets, or ndfeb rare earth magnets, are with amazing strong magnetic power. The neodymium is a kind of rare earth element that mainly used to compound with iron and boron.
Main Manufacturing process of ndfeb magnets Â
1.Pressing ndfeb garins: pressing process was operated in strong magnetic environment.Â
2.Sintering of ndfeb blocks: sintering was processed in a vacuum furnace.
3.Wire cut: ndfeb magnet are fragile materials,usually specified dimensions was required, genneral cutting process could not reach the standard of sizes,usually cutting process had operated in wire cut machines.Â
4.Grinding process: Grinding process: To reach the tolerance, a diamond polish tool is needed.Â
5.Plating: Neodymium magnets had been treated with electrical plating,otherwise it will rust in the air. Platings that have been successfully applied to neodymium magnets are epoxy plating,nickel plating,NICUNI plating,zinc palting and even silver plating and gold plating.Â
6.Magnetization:the procedure are processed with magnetization machine which have a magnetic feild ranged from 2~100 koe.
