Impact Testing Low Temperature Chamber

Application:

DWC Series Temperature Chamber is designed according to the standard of 'Charpy Notch Impact Test
Method for Metal Materials' and adopts compressor cooling technology, which is made up of two sections
(Low temperature grade and high temperature grade). It utilizes the heat balance principle and cycle stirring
method to realize the constant temperature cooling to impact specimen with the reliable performance.
