Corrosion test machine and SO2 Gas Salt spray tester JOEO designed with Programmable color LCD touch screen controller Ethernet connection, PC Link and Temperature Sensor. It has Centrifugal wind fan. Cyclic corrosion tester are used in many industries as they help in corrosion resistant of the products. Salt fog is the dispersed system made up of tiny liquid drop which contains salt in air. It is used to create manual simulation salt mist environment to test anti-corrosion resistance of materials.
