Shanghai Test Instruments Co., Ltd. [China]

1. High Value 2. Good quality 3. Easy to operate 4. Two years warranty

Main Feature:

Model JB-300B impact testing machine is the use of pendulum impact test before and after impact the remaining potential energy potential energy difference shown in the dial on the way, get the test patterns of the absorbed energy.

The device works by Charpy impact before and after impact the impact of potential energy to detect the difference between the absorbed energy, the material toughness. Display for the dial pointer display; the equipment operating on semi-automatic control, in the course of the experiment electric Jan swing, impact, and the use of thrust energy remaining after the sample can be placed automatically Young. Easy operation, high efficiency, in a continuous pattern of doing impact test, the better to reflect its superiority.

Applicable Industry:

This machine is suitable for mechanical metallurgy, aerospace, universities, research institutes and other areas used to measure the impact toughness of metallic materials and metal materials in the dynamic load shock resistance. Widely used in scientific research units.
