Roll Hardness Tester

The coil hardness tester applies pressure to the surface of the coil through an indenter and converts the hardness value based on the depth or diameter of the indentation. It is used to test the compressive resistance of materials such as films and coatings, and is employed in the plastic and printing industries for quality control.
Selection
When selecting, consider matching the thickness and hardness measurement range of the coil; use a spherical indenter for soft materials and a conical one for hard materials. Environmental temperature and humidity affect accuracy, so choose a suitable model accordingly. Portable types are suitable for on-site testing, while benchtop models are ideal for laboratories.
