** Cooling range: room temperature ～﹢30- -60℃

** Constant temperature accuracy: ＜±0.5℃



This machine is a newly researched and developed cooling machine for impact sample according to low temperature device in GB/T229-1994. This device uses overlapping compressor refrigeration technique and thermal equilibrium principle any cycle stir, to make the specimen automatic uniform cooling and constant temperature.

** Types of processed specimen notches V-types, U-type (2mm)

** Original billet size of processed specimen: 10 × 10× 55mm



During the impact test of Charpy notches on metal materials, processing quality of the specimen notches is one of the critical factors that influence whether the test is accurate.

** Semi-automatic type and automatic type impact testers

** Impact energy 500J



This machine is mainly used to test the impact resistance performance of the metal materials under live load, being an indispensable testing instrument in metallurgy and machine manufacturing units and is also a necessary testing instrument for the research of new materials in research institutions.

** Computer display type and automatic type impact tester

** Impact energy 150J, 300J



This machine is mainly used to test the impact resistance performance of the metal materials under live load, being an indispensable testing instrument in metallurgy and machine manufacturing units and is also a necessary testing instrument for the research of new materials in research institutions.

** Digital display semi-automatic type impact tester

** Impact energy 150J, 300J


This machine is mainly used to test the impact resistance performance of the metal materials under live load, being an indispensable testing instrument in metallurgy and machine manufacturing units and is also a necessary testing instrument for the research of new materials in research institutions.
