Low temperature slot for drop hammer tear impact test

The HL-80 impact test low-temperature test is a compressor refrigeration equipment developed by our company based on the requirements for low-temperature devices in GB8363-07 "Method for Drop Weight Tear Test of Ferritic Steel".

HL-80The low-temperature discussion for impact testing is based on our company'sGB8363-07A compressor refrigeration equipment developed in accordance with the requirements for low-temperature devices in the "Method for Falling Weight Tear Test of Ferritic Steel". This equipment adopts a cascade compressor refrigeration technology, utilizing the principle of thermal balance and circulating stirring to achieve automatic uniform cooling and constant temperature of the sample, fully meeting the temperature control indicators specified by national standards. This low-temperature tank adopts single-chip microcomputer technology control, digital temperature value display, automatic temperature control, automatic timing, and automatic alarm. It is easy and safe to operate, with fast cooling speed, large volume, and high temperature control accuracy. This machine only requires a power supply and does not require water or liquid nitrogen, making it an ideal sample cooling and insulation device for low-temperature impact testing of metal materials.
Meet the requirements of American and European standardsASTM E23-02a、EN10045、ISO148、ISO83Waiting for relevant international standards.
