Sponge foam indentation hardness tester,Sponge collapsible fatigue tester
1. 使用:
This machine is used to measure the concave hardness of porous elastic materials. Polyurethane sponge foam sample can be determined by the national standard test, accurate measurement of sponge, foam and other materials such as compression hardness. 此外, it can also be used to measure the specified indentation hardness of the produced seat foam (such as backrest, seat cushion foam, ETC。), and accurately measure the indentation hardness of the foam parts of the seat.

二, 原则:
Sponge foam compressive stress test will be placed in the sample between the upper and lower pressure disc, the upper pressure disc at A specified speed downward compression of a certain size of sample to the national standard requirements of A method (B method, C method) of the concave degree, the load element on the induced pressure feedback to the controller processing and display, so as to measure the sponge, foam samples and other materials such as the indentation hardness.

三, functional characteristics
1. Automatic zero clearing: After receiving the instruction to start the test, the system will automatically clear zero.
2, automatic return: after the sample fracture, automatic return to the initial position.
3, change the speed: This machine can be according to different samples, arbitrarily change the test speed.
4. Indicating value verification: the system can realize the accurate calibration of force value.
5, control method: according to the needs of the test can choose test force, test speed, displacement and other test methods.
