GH-D Electronic Thickness Tester is designed and manufactured according to GB 6672, ASTM D645, ISO 4593, and applicable in accurate thickness test of all kinds of materials in its test range. Features Mechanical test method, no restriction of testing materials. Testing accuracy up to 0.1 micron contacting area and pressure between testing head and film conform to the relative standards strictly. Special configuration design guarantees the parallel of the upper and lower test surfaces. LCD displays test parameters, operation buttons friendly design. settable test models of manual and automatic. Statistics and automatically print test result. Compatible with ISO, ASTM and multifold test standards for film thickness. Structure This micrometer is made up with control system, test system, print and output system. Test system is for testing specimens and output of electrical signal. Control system is applied for setting and modification of parameters, signal processing, result displaying and so on. Output system\'s function is to print out the result. Principle This thickness gauge employs the most advanced technology in the world, to guarantee the accuracy of the test result and high consistency of several test results. Easy operation is approximately automatic, decreasing the influence to test result caused by manual factors. Print out test result of single test. Process, analyze, and print out test result of batch of tests. Contacting area, test pressure, and moving speed conform to relative standards strictly. Specifications Test range: 0~5mm(normal) Resolution: 0.1μm Sample spacing:0~1000mm Measurement points: 0~10points Power supply: 220V, 50Hz
