LDW-80T Falling Impact Testing Low-temperature Meter
Usage and Characteristics
LDW-80T Type Impact Testing Low-temperature Meter is newly researched and developed compressor refrigeration plant according to requirement of low temperature device in GB/T8363-2007 (metallic materials-drop weight tear tests of ferrite steels).
GB/T229-2009 (metallic materials-Charpy notch impact testing machines). The device adopts refrigeration technology of cascade compressor, taking advantage of principle of heat balance and loop mixing method to achieve automatic uniform cooling and constant temperature for samples and the temperature indicator can meet the national standard completely. The machine is controlled by intelligent instrument, digital presentation temperature value, automatic control temperature, is the ideal device for specimen cooling and heat preservation in metal low temperature impact test which also can satisfy American standards and European standards, like ASTM, E23-02a, En10045, ISO148, ISO83 and so on.
