Product name：CDW  series Impact testing low temperature instrument 

Product introduction

Low temperature impact test is an important test of mechanical performance of metal materials, the accuracy of the test temperature directly affects the reliability of.CDW type test data at low temperature impact test instrument (slot) is a company based on GB/T229-2007< metallic materials Charpy pendulum impact test method (GB/T229-1994< > alternative metal Charpy Notch Impact Test Method ") to the requirements of low temperature the device, with the provisions of the deep temperature refrigeration, and the latest development, the application of suitable metal products of low temperature chemical testing new products. The equipment adopts single / cascade refrigeration compressor, using the principle of heat balance and circulation agitation method to achieve automatic uniform cooling, the sample temperature, can be completely various technical indicators meet the requirements of the national standard GB/T229-2007. This equipment is simple and convenient operation, high work efficiency, is the most ideal metal sample cooling and low temperature impact test, Constant temperature equipment. Can also be used for other low temperature detection and test work. Ultra low temperature refrigeration cycle using the three element cascade, greatly expanded the work of the circulatory system temperature, than the traditional double stage compressor cycle lower refrigeration temperature (100 DEG C rapid cooling). This equipment has adopted a comprehensive new environment-friendly refrigerant, provides convenience for the future maintenance inspection, is the domestic impact test fields the most mature ultra low temperature refrigeration equipment
