AbstractThe HST DWC-80T is a Touch Screen display Impact Test Low Temperature Chamber built for Charpy notch impact testing of metal materials: it cools a batch of up to 72 standard impact specimens to a set point anywhere in the +30 to -80deg C range, holds it with ±0.2deg C control accuracy, and keeps the specimen at temperature for the immersion time the protocol calls for. Compressor refrigeration (an imported Europe Embraco compressor), a cycle-stirring heat-balance design and a touch-panel controller with automatic time and alarm functions are the three things the machine is built aroun
