一、 Equipment name: Microcomputer screen display semi-automatic impact testing machine

二、 Model: JBW-500B

三、 Performance Description:

This machine is mainly used to measure the impact resistance of metal materials under dynamic loads, in order to determine the properties of materials under dynamic loads.

This machine is a semi-automatic impact testing machine with a microcomputer screen display. It is controlled by a PC microcomputer and features electric swing, impact, microcomputer measurement, calculation, screen digital display results, and can be printed. It has high work efficiency and testing accuracy.  After impacting the sample, the remaining energy can be used to automatically swing and prepare for the next test. The operation is simple and the work efficiency is high.  Its superiority can be better demonstrated in laboratories that conduct continuous impact tests and in industries such as metallurgy and mechanical manufacturing that conduct a large number of impact tests.  Computers can calculate and display the impact absorption energy, impact toughness, pendulum swing angle, and test average value of materials, and can print the test data and average value for the current test.
