Product Description:
The machine consists of an instrumented impact testing machine, a liquid nitrogen cooling device, and an automatic feeding positioning device, which is used to accurately test and analyze the impact resistance of materials at low temperatures.
The low-temperature device adopts liquid nitrogen refrigeration, with a cooling temperature up to -190°, fast cooling speed, automatic temperature control, automatic alarm prompt, and compressor are original imported brand machines.
The sample box can hold 20 samples at a time.
The feeding and positioning is carried out by pneumatic or electric, with fast speed and accurate positioning.
