Usage and Characteristics

LDW-80T-Z type drop hammer impact test low temperature chamber is the latest compressor refrigeration equipment developed by our company according to the requirements of GB8363-07 "Temperature Steel Drop Weight Tear Test Method" for cryogenic equipment.

The equipment adopts the compressor refrigeration technology, and uses the principle of heat balance and the stirring circulation mode to achieve automatic uniform cooling and constant temperature of the sample, which can fully meet the various temperature control indexes stipulated by the national standard GB8363-07. The door can be electrically opened and closed, and it can be matched with the manipulator to take the sample.

The equipment is simple and convenient to operate, and has high work efficiency. It is the most ideal sample cooling and heat preservation equipment for metal low temperature impact test. It can also be used for other low temperature testing and testing work.
