Hardness Testers, Material Hardness Testing Instruments, for Measuring the Hardness of coatings, Plastics, Wood, and Metal Surfaces, Flat and Curved Surfaces

This hardness tester accurately measures and records the hardness of various materials, including coatings, plastics, wood, and metals. Specifications: Pressure test spring material: Spring steel Test heads material: Tungsten carbide Test heads diameter: 0.75mm Spring pressure range: 0N to 3N (marked in blue) 0N to 10N (marked in red) 0N to 20N (marked in yellow) Package List: 1 x Hardness Tester

• Spring compression: The spring generates a specific force on a test probe with a known diameter, creating a scratch on the surface of the coating to assess potential damage. Results are measured in Newtons.This pen accurately measures and records hardness levels of various materials, including coatings, plastics, wood, and metal. Suitable for testing both flat and curved surfaces.
• Measurement principle: The pen applies a controlled force to the surface, creating a scratch that indicates the material's hardness. A pronounced scratch indicates higher hardness, while a faint or absent scratch indicates lower hardness.
• Simple operate: The test probe produces a visible scratch line. The clarity of the scratch varies with the applied pressure: higher pressure results in a more defined scratch, while lower pressure produces no scratch. The sliding rod allows for precise pressure control, measured in Newtons.
• Advantages and applications: This tool is widely used in various industries for quality control and material testing, ensuring compliance with hardness specifications. Its ability to measure hardness on both flat and curved surfaces enhances its versatility for testing.
