Pen Type Hardness Tester, Surface Scratch Tester, with 0.75mm Test Head, Pressure Spring, for Coatings Plastics Wood Metal Materials

Used to accurately measure and record the hardness of various materials (such as coatings, plastic, wood or metal surface hardness) Specifications: Pen body: stainless steel Pressure test spring material：Spring steel Test head material：Tungsten carbide Test head diameter: 0.75mm Spring pressure range：0~3N (marked in blue)；0~10N (marked in red) ；0~20N (yellow mark) Product Includes: 1*Hardness Tester

• ▲Newton hardness tester pen, used to accurately measure and record various hardness (such as the hardness of various coatings, wood, metal and other materials). The measuring surface can be flat or curved, and the test can be completed regardless of size
• ▲At a speed of 10mm/s, draw a straight line of 10 to 20mm vertically on the sample. In this way, the surface hardness of the product is judged to be less than the Newton scale of the current hardness tester
• ▲The spring is compressed and deformed, and the load is applied to the test head of known diameter. The test head is used to mark the surface of the coating to be tested to check whether the coating surface is damaged
• ▲Uniform hardness and good coating quality facilitate smooth production. This instrument is specially used to measure the hardness of protective coatings
• ▲Hardness testing provides engineers, plumbers, surveyors and other related personnel with testing instruments that meet various smooth production operation requirements
