DWC-60 Impact Test Low Temperature Tank/Instrument
A specialized refrigeration equipment developed in accordance with the requirements for low-temperature devices for impact specimens in GB/T229-2009 "
Product details

Product Introduction


A specialized refrigeration equipment developed in accordance with the requirements for low-temperature devices for impact specimens in GB/T229-2009 "Charpy notch impact test method for metals" fully meets the temperature control indicators specified in GB229-2009, ASTM, En10045, and ISO83.
This equipment adopts a cascade compressor for refrigeration, utilizing the principle of thermal balance and circulating stirring to achieve automatic uniform cooling and constant temperature of the sample. The equipment is easy to operate, with high work efficiency. It is controlled by single-chip technology, digital temperature value display, automatic temperature control, automatic timing, and automatic alarm. The operation is simple and safe, the refrigeration speed is fast, the volume is large, and the temperature control accuracy is high. It is an ideal sample cooling equipment for low-temperature impact testing of materials.
