LDW-80T Falling Impact Testing Low Temperatue Chamber


LDW-80T Falling Impact Testing Low Temperatue Chamber

Usage and Characteristics
LDW-80T Type Impact Testing Low-temperature Chamber is newly researched and developed compressor refrigeration equipment according to requirements of low temperature device in GB8363-2007The device adopts refrigeration technology of cascade compressor, taking advantage of the 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, automatic time and alarm, easy to operate, prompt refrigerating speed, capacious working space, high-precision control temperature, is the ideal device for specimen cooling and heat preservation in the metal low temperature impact test which also can meet American and European standard ASTM E23-02a,EN10045,ISO148,ISO83 and so on.
