JBS-300CD Digital Automatic ultra-low temperature impact testing machine
This series of impact testing machine for the performance of metallic materials at very low temperatures to resist the impact of inspection, metallurgical machinery and other units of the necessary testing equipment, also new materials research unit indispensable test equipment.
The machine number explicitly automatic impact testing machine, using SCM and control, electric Yang pendulum, impact, computer measurement, calculation, the number of significant results can be printed, high efficiency, high precision After the impact of the sample can be Surplus energy use automatic Yang pendulum, ready to do the next test, easy operation, and high efficiency. In doing continuous impact test lab and do a lot of impact test metallurgy, machinery manufacturing and other industries to better reflect its superiority. microcontroller Digital material impact absorbed energy, the pendulum Yang angle and test average value, and can print test data and average value when the second trial. using liquid nitrogen cooling, the temperature adjustment are electrical control, with a special automatic feeding device to send samples, Automatic face orientation sample, sample baked to ensure impact time is less than two seconds, meet the requirements of low-temperature metal Charpy impact test method.
