TN4228 Programmable Foam Hardness and Stress Tester
INTRODUCTION
It is used to measure the long-term low-cycle compression fatigue properties of soft materials (sponge, foam, etc.), and can also be programmed to measure the collapsible hardness index, collapsible hardness characteristics, sag hardness test, stress-strain characteristics, etc.
Applicable to the relevant standard method A, B, C and special standard requirements, specifications.
Can be used for polymer porous elastic materials, polymer materials, metal and non-metal tensile, compression, bending, low cycle fatigue and other items of detection, can obtain the compressive hardness index, compressive stress, maximum test force, yield force, compressive strength, bending strength and other parameters.
FEATURES AND BENEFITS
1.Automatic calibration : can automatically realize the calibration of the value standard degree, optional international units of kgf, lbf, N, KN, Kpa; Mpa, mm, cm, inch.
