Hand crank type is easy to operate, load 1000g +/- 1g, scratch speed about 1mm/s, test angle 45 °, standard 6B-6H pencil, in line with a number of international standards, through the pencil Hardness grade to accurately evaluate the scratch performance of the paint film.
The pencil scratch method is used to test film Hardness, and the three-point contact design always guarantees a 45 ° angle, which meets the GB6379 standard and is suitable for film Hardness detection in laboratories and construction sites.
Using electric Dial design, the scratch length can reach 60mm, the load range is 0-2000g, and the physical characteristics of the coating are characterized by the anti-penetration ability of the scribing needle.
Using digital touch screen control, the test speed is adjustable from 0-40mm/s, the load range is 0-4000g, the minimum increment is 50g, and it is equipped with a variety of weights and special scribing needles to accurately determine the film scratch resistance performance.
Adopt 45 ° test angle and adjustable load system, the test platform traverse speed 0.5-10 mm/s adjustable, equipped with LCD display real-time monitoring, to meet the needs of accurate coating Hardness detection.
Control system using servo motor, scratch speed 254mm/min, weight free lifting, ensure that the needle parts accurately fall on the workpiece, to achieve automatic scratch and zero operation.
Three-point contact design ensures 45 ° stability testing angle, equipped with 6B-6H pencil and 500g to 1000g adjustable load, manual push to achieve accurate film Hardness identification.
The three-point contact design ensures a 45-degree test angle and provides a 500/750/1000g three-speed load for rapid determination of coating Hardness and is suitable for laboratory and field environments.
The three-point contact structure is used to ensure stable sliding, the test angle is fixed at 45 °, and the 500/750/1000g adjustable load is equipped. The coating Hardness is accurately judged by the scratch depth of different Hardness pencils.
The scribing needle is used to act vertically on the film, the load range is adjustable from 0-2000g, the minimum increment is 50g, and the diaMeter of the steel ball is 1mm, which can accurately determine the minimum weight required to cut the paint film.
Steel ball diaMeter 1mm needle, load range 0-2000g, through the minimum load of the film to accurately determine the coating resistance to penetration, traverse speed 30-40mm/s to ensure the test Stability.
Equipped with Φ 1mm, Φ 0.75mm, Φ 0.50mm three probes and 0-30N spring pressure, using wheel handle design, can be quickly measured in plane and curved surface, no maintenance and anti-corrosion.
Adopt 0.75mm tungsten carbide test head, provide 0-20N three-gear adjustable pressure, accurately detect coating Hardness by scratch method, suitable for different curved surfaces and durable structure.
The 45 ° fixed angle design is adopted to ensure that the cylindrical pencil lead maintains a constant angle and pressure, the load is 500g, the error is +/- 10g, and the coating Hardness level is determined by the minimum Hardness value pencil trace.
Equipped with 20 different Hardness pencils, covering the range of 8B to 10H, made of stainless steel, supporting 750g to 1000g load, according to Wolff Wilborn specification measurement coating scratch resistance.
