The impact test low-temperature instrument is a refrigeration equipment developed based on the requirements for low-temperature devices in GB229-2007 "Metallic Charpy notch impact test method". This impact test low-temperature instrument adopts liquid nitrogen refrigeration technology and utilizes the principle of thermal equilibrium to achieve automatic uniform cooling and constant temperature of the sample, which can fully meet the temperature control indicators specified in the national standard GB229-2007. This low-temperature impact tester is easy to operate and has high work efficiency, making it the most 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. Technical parameters:
