DWC Impact Testing Low Temperature Chamber (Liquid nitrogen)
This equipment used liquid nitrogen refrigeration 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.
Standards：
ASTM, E23-02a, En10045, ISO83，GB/T229-2009
Features：
It uses liquid nitrogen cooling technology and high-precision intelligent instrument to control ultra-low temperature test
It can achieve automatic uniform cooling and constant temperature for specimen
