The DWC-60 impact test low-temperature test is the latest compressor refrigeration equipment developed by our company based on the requirements for low-temperature devices in GB229-2002 "Metallic Charpy notch impact test method". This equipment adopts imported Taikang dual compressor refrigeration technology from the United States, using the principle of thermal balance and circulating stirring to achieve automatic uniform cooling and constant temperature of the sample, fully meeting the temperature control indicators specified in the national standard GB-229-2002. This device is easy to operate and has high work efficiency, making it the most ideal sample cooling and insulation equipment for low-temperature impact testing of materials. It can also be used for other low-temperature detection and testing work.
