1.Usage
The JB-50D LCD display impact tester is a single-chip microcomputer control, liquid crystal display type. The instrument has convenient man-machine dialogue, high accuracy, automatic display of impact energy, automatic calculation of impact strength, and automatic calculation of the average value of the impact strength of the entire set of samples, and data can be arbitrarily deleted. Equipped with a printer. Electric release hammer body. The whole machine has good rigidity and no stress deformation after aging treatment. Used to measure the impact toughness of non-metallic materials and metal materials such as hard plastics, fiber reinforced composite materials, nylon, glass steel, ceramics, cast stone, plastic appliances, insulating materials, cast iron, non-ferrous metals, etc. It is a commonly used equipment for quality inspection in scientific research institutions, universities, and related factories and mines.
