Foam Hardness Meter

The sponge hardness tester applies pressure to a sponge sample through an indenter and measures its degree of deformation to reflect the hardness value. It is used to evaluate the support performance of soft materials such as sofas and mattresses, and to determine whether the softness or hardness of the product meets standards in quality inspection and production control.
Selection
Select the indenter size based on the thickness of the material being tested, determine the measurement range according to testing standards, choose between mechanical or digital display types considering the operational environment, verify whether the instrument's accuracy meets the testing requirements, and confirm the validity of the calibration certificate.

Pencil Hardness Tester for Rapid Evaluation of Coating Surface Hardness
The pencil hardness tester is a tool used for rapidly assessing the relative hardness of coating surfaces through standardized scratch tests. It employs a series of pencil leads with known hardness levels, which are drawn across the coating under a fixed load and angle. The hardness grade, ranging from 6B to 9H, is determined based on whether a permanent scratch is produced.
Buchholz indentation tester measures the indentation hardness of varnish.
The Buchholz indentation test is a method for measuring the indentation hardness of coatings such as varnishes. It involves applying a specific indenter to the coating surface under a standard load, and after unloading, the length of the residual indentation is measured. A longer length indicates lower hardness.
Pencil Hardness Plan Outstanding Paint Film Pencil Hardness Grade
The pencil hardness test is a method for evaluating the scratch resistance of paint films. It involves using a series of pencils with known hardness levels to scratch the coated surface under fixed conditions. The hardness grade of the coating is determined by observing whether permanent scratches are produced.
The pendulum hardness tester tests the scratch resistance limit of varnish.
The pendulum hardness tester measures the hardness of varnish by observing the attenuation of the pendulum's swing on the coating surface, with faster attenuation indicating a softer coating. The scratch resistance of varnish depends not only on hardness but also on elasticity and toughness. Hardness testing sets the basic threshold for scratch resistance.
Application of Film Pencil Hardness Tester in Coating Scratch Resistance Testing
