CDW-80T Pendulum Impact Testing Low-temperature Chamber(Low-temperature tank)

CDW-80T Pendulum Impact Testing Low-temperature Chamber(Low-temperature tank) is the compressor refrigeration of the latest research and development in accordance with cooling requirement of GB229-2007 "metal Charpy notched impact test method". This equipment used cascade refrigeration compressor technology, the use of the principle of heat balance and mixing method of circulation to achieve uniformity of the sample auto-cooling and temperature, to fully meet the temperature indicators of national standard GB229-2007 and American standard, European standard ASTM E23 - 02a, EN10045, ISO148, ISO83 and other stipulated specifications related in the standard of temperature control index of the provisions. The equipment is simple, convenient and efficient for working, which is the ideal equipment of specimen cooling and insulation for low-temperature impact testing. At the same time, it can also be used for other low-temperature detection and testing.
