Scratch Hardness Tester – Hand Operated

Presto’s Scratch hardness tester is an effective tool used to perform tests related to scratch resistance under a specified load. It can be used for diversified products like lacquers, varnishes, and paints. The tester is recommended mainly for paint and plating industry and designed especially for small laboratories where continuous quality control tests need to be conducted.

Hardness can be explained as a material’s resistance to permanent deformation. In the coating industry, this measurement can be used to measure the resistance of the coating to scratch from normal wear and tear and also if the coating is fully protected. The term Hardness is used to explain the various properties of material, namely – Resistance to scratch & wear and Resistance to penetration.

As per the requirements, these are different methods for measuring hardness. Some of them are used for measuring coatings, and others are used to test various bulky materials like plastics, metals, elastomers and rubbers.

The test procedure for laboratory testing equipment is carried out by testing a sample at a specified load on the needle or by enhancing the weight to conclude the minimum load at which the coating can be pierced. It is a highly reliable and durable instrument. The testing instrument conforms to ISO standards and available with conformance certificate along with instruction manual.

    Use of scratch hardness tester helps me a lot for improving the quality of the paints. The weak paints scratches easily with the slight rubbing and that was the main issue for my customers. The device helps me to locate the right quality of the paints that can resist the different conditions.
