JBD-300YI Low temperature fully automatic impact testing machineDetailed product description：

The JBD-300YI low-temperature impact testing machine is used to test the impact resistance performance of metal materials under dynamic loads. It is an essential testing instrument for metallurgical machinery manufacturing and other units, as well as an indispensable testing instrument for research institutions conducting new material research.

JBD-300YI is a fully automatic impact testing machine with electric swing and impact, and can use the remaining energy after punching the sample to automatically swing and prepare for the next test. It is easy to operate and has high work efficiency. 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. The JBD-300Y Ⅰ low-temperature impact testing machine adopts a cascade compressor refrigeration technology, utilizing the principle of thermal equilibrium and cyclic stirring to achieve automatic uniform cooling and constant temperature of the sample, fully meeting the temperature control indicators specified in the national standard GB/T229-2007. This device is easy to operate and has high work efficiency, making it an ideal sample cooling and insulation equipment for metal low-temperature impact testing. It can also be used for other low-temperature detection and testing work.
