LDW-80T Impact Test Low Temperature Chamber
Low Temperature Chamber
Application of Equipment
LDW-80T Impact Test Low Temperature Chamber is the compressor refrigeration equipment newly developed by our company according to the requirements for low temperature devices in JB-5376-1991 Technical requirements of low temperature constant temperature tank and GB/T 8363-2018 Steel-Drop-weight tear tests method. This equipment adopts cascade type compressor refrigeration technology, heat balance principle and circulating stirring method to achieve automatic cooling uniformly and constant temperature of the test specimens, which can fully meet the various temperature control indicators stipulated in relevant standards. This equipment adopts single chip microcomputer technology control, digital display temperature value, automatic temperature control, automatic timing, automatic alarm, simple and safe operation, fast cooling speed, large volume, high temperature control accuracy, which is the most ideal equipment for metal material in low temperature impact test sample cooling and heat preservation equipment. It can also be used for other low-temperature detection and test work.
