Product description:

CDW series impact test temperature trough

Low temperature impact test is a metallic material is very important mechanical properties test, the accuracy of the test temperature directly affects the reliability .CDW type impact test temperature meter test data (groove) is a company based on GB / T229-2007 (metallic materials Charpy pendulum impact test methods) (instead of GB / T229-1994 (metal Charpy notched impact test method)) required for cryogenic device, with the provisions of the deep temperature cooling, and the latest development, the development of suitable metal New Products Products Physical Testing of hypothermia. The device uses single / cascade compressor refrigeration technology, the use of heat balance principle and circulation mixing method, to achieve automatic uniform cooling of the sample, temperature, can fully meet the national standard GB / T229-2007 under the various technical indicators. The device is simple and convenient operation, high efficiency, is the sample cooling, thermostatic temperature impact test equipment metal ideal and can also be used for other low-temperature testing and experimental work. use ternary cascade ultra-low temperature refrigeration cycle technology, which greatly expanded the temperature difference cycle work, accessible than the traditional two-stage compressor refrigeration cycle lower temperature (-100 ℃ rapid cooling). At the same time, this device has fully adopted the new environmentally friendly refrigerants for future inspections and repairs to provide a convenient, it is currently the most mature areas of impact testing ultra-low temperature refrigeration equipment
