上海超声波仪器厂试制成功的CCH-10型超声波测厚仪是一种袖珍式数字显示的通用测量仪器,采用脉冲反射法进行测厚。该仪器具有单面无损测厚的独特功能,对于声衰减不太大的材料,如钢、铝、铜、铅等金属,玻璃、有机玻璃、瓷器、胶木和部分硬质塑料等都可以进行测厚。尤其对船体、管道、钢管、高压容器、大面积平板的中间处,以及无法同时触及材料两面的物体,能测出正确的壁厚。该仪器的测量范围为1.5~99.9毫米(钢);1~30毫米(有机玻璃)。近距离灵敏度可测直径30毫米、厚
Shanghai Ultrasound Instrument Factory trial successful CCH-10-type ultrasonic thickness gauge is a pocket-sized digital display universal measuring instruments, using pulse reflection method for thickness measurement. The instrument has a unique single-sided non-destructive thickness measurement of the function, the sound attenuation is not too large for materials such as steel, aluminum, copper, lead and other metals, glass, plexiglass, porcelain, bakelite and some rigid plastic can be measured thick. In particular, right hull, pipe, steel pipe, high pressure vessels, the middle of a large area of the plate, and can not touch both sides of the material at the same time, can measure the correct wall thickness. The measuring range of this instrument is 1.5 ~ 99.9mm (steel); 1 ~ 30mm (plexiglass). Close-range sensitivity can be measured diameter 30 mm, thick
