1 limpact testing machine
2 used imported Thailand Kang compression engine refrigeration technology of USA.
3 lowest to -196

1). CDW-196-type low-temperature impact testing instrument are the Liquid nitrogen refrigeration of the latest research and development in accordance with cooling requirement of GB229-94 "metal Charpy notched impact test method". This equipment used imported Thailand Kang Shuang compression engine refrigeration technology of the USA, 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 GB229-94 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.
