【Abstract】 Plating and coating technique are more widely used along with the development of the material science and industry. A precision, real-time and non -destructive testing method is establishing and a digitized and intelligent thickness meter JCH-3a is developed for measuring the layer thickness. The JCH-3a meter consists of a high accurate probe, very large scale integrated circuits and a built-in microcomputer. Its special features are: 1. digital display of the measured data; 2. preseting the limitation of warning values and automatic storing the measured data; 3, output of printing data; 4. broad measuring range; 5. small in size and light in weight. It can be also used in the thickness measuring of the reactor components.更多还原
