Ⅰ Device name: CDW-30 Low Temperature Impact Test meter
Ⅱ Model: CDW-30
Ⅲ Usages and characteristics:
CDW-30-type low-temperature impact testing instrument 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 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 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.
