• [Mohs Hardness Pen]: According to the hardness of different minerals, materials of different hardness are selected to simulate alternative minerals to make scratch pens similar to minerals, which are used to test the Mohs hardness of various material surfaces
• [4pcs Hardness Test Pens]: There are 4 hardness pens in the box. Each hardness pen has writing needles with different hardnesses at both ends. The scales according to Mohs hardness are: 2&3, 4&5, 6&7, 8&9
• [Mohs Hardness Test Method]: Keep the pen at about 70 degrees from the ground, press the tip of the hardness pen, and make a scratch test on the surface of the object to be tested. Draw a straight line of about 20mm and judge the relative Mohs hardness level of the object being tested by observation
• [Premium Material]: Made of pure stainless steel, with good texture and exquisite appearance. There are 4 hardness pens in the box, each 155mm long. Hardness test kit is a multi-faceted shape carefully processed so that will be more convenient and durable to use
• [Application]: Commonly used for Mohs hardness determination on the surfaces of various types of solidified floors, floor tiles, ceramic tiles, concrete floor construction industry, glass, ceramics, marble products, ores and minerals, jewelry and jade artifacts, industrial porcelain
