Application of Equipment
The CDW-80 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 229-2007 Metallic materials-Charpy pendulum impact test method. This equipment adopts imported compressor refrigeration technology, and 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 GB/T 229-2007, and the American standard ASTM E23-2018, European standard EN10045 and ISO148 etc. 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 material in low temperature impact test sample cooling and heat preservation. It can also be used for other low-temperature detection and test work.
