Pencil Hardness Tester QHQ-A Kit – Coating Film Scratch Tester with 13 Pencils & Weights for Paint Abrasion Testing, Complies with GB/T 6739-2006 & ISO 15184

Product OverviewThe QHQ-A pencil hardness tester is a professional coating hardness testing instrument designed and manufactured in accordance with the national standard GB/T 6739-2006 and the international standard ISO 15184:1998. This kit adopts the internationally recognized pencil scratch method, providing precise and reliable coating hardness testing solutions for industries such as coatings, painting, plastics, and metal processing. The instrument features a mechanical three-point contact design, ensuring that the test process always maintains a 45-degree standard angle. The test results are presented intuitively in standard pencil grades (6B-6H), making it an ideal tool for quality control, R&D testing, and on-site acceptance.Standardized DesignCompliance with International Standards: Strictly designed and manufactured in accordance with GB/T 6739-2006 and ISO 15184:1998 standards. Three-point contact structure: Two rollers and one pen core form a stable three-point contact, ensuring that the test angle remains constant at 45°. Pencil hardness scale system: The test results directly correspond to the standard pencil hardness grades, facilitating data comparison and recording. Complete Test SuiteThis suite includes all the components required for testing: The main body of the QHQ-A pencil hardness tester is made of high-carbon steel structure, weighing only 1.2kg, with dimensions of 200×80×60mm. A set of 13 standard test pencils: covering the complete hardness series of 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 2H, 3H, 4H, 5H. Adjustable weight sets: 500g, 750g, and 1000g specifications, meeting the requirements of different standards. Precision sharpener: For standard sharpening of pencil tips to ensure test accuracy. Specialized storage box: All components are neatly stored in order, facilitating carrying and management.
