impact V U notch gap Low temperature chamber for impact test

 CDW series pendulum impact testing low-temperature champer tank is according to cooling requirement of GB229-2007 "metal Charpy notched impact test method". This device includes compressor refrigeration and liquid nitrogen refrigeration. Compressor cooling takes the advantage of the principle of heat balance and loop mixing method to achieve automatic uniform cooling and constant temperature for samples. The refrigeration mode of ultra-low temperature equipment adopts mainly liquid nitrogen refrigeration, using the performance of ultra-low temperature of liquid nitrogen, based on heat balance principle, to achieve automatic uniform cooloing. The temperature indicator can meet the national standard completely. It can also satisfy American stanards and European stanards, like ASTM E23-02a, EN10045, ISO148, ISO83 and other international relative standards.
