JBW-H series instrumented impact tester is adopts advanced foreign technology and cooperate with China National Engineering & Physical research institute to developed a new products. Through measuring the impact value, collect and analysis the impact process data, figure energy curve, then supply details data for engineers to study and analysis material character.
This tester is mainly consist of automatically high and low temperature device (optional), auto-feeding system, and impact tester load frame, can be used test, analysis the accuracy material anti-impact performance. Tester is controlled by computer, rising pendulum, hang pendulum, impact, stop all controlled by PC.
Adopt data collection system, change the voltage signal to digital signal, add data storage and PC, to transfer collected data to impact load - time, impact load-displacement, displacement- time, energy- time etc. curve. Vivid illustrate the material under loading and deformation process to break.
