Microcomputer controlled low temperature automatic impact testing machine

Introduction

Microcomputer-controlled low-temperature automatic impact testing machine is an instrument for testing the impact resistance of metal materials under dynamic load. It can continuously do a large number of metal impact tests, adopt automatic control, and control the whole process of swing and impact tests through microcomputer software programs. Display impact absorption work, impact toughness, rotation angle of pendulum and print test report, etc. The operation is simple, safe and reliable, and the work efficiency is high. It is equipped with two pendulums, which can be replaced according to the test requirements, and has met the requirements of the national standard for the test range of the impact machine. This machine is equipped with a protective net cover, which provides conditions for the safe operation of users. It is an indispensable testing instrument for metal material manufacturers and quality inspection departments, and it is also an indispensable testing instrument for scientific research units to study new materials.
