Mohs' Hardness Test Kit for Industrial Use

While the Mohs' Hardness test was developed originally for testing minerals, the same concept can be applied to industrial materials.  Use this kit for "scratch testing" substances to determine their Hardness according to the Mohs' Hardness scale, which ranges from 1 to 10, where Diamond is the hardest at 10, while Talc is softest at 1.

How do you use the hardness picks? Simply scratch a smooth surface of your material with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the material, but a No. 4 pick does not, then your material’s hardness is 4.5.

Includes:

• Four double-ended picks, color-coded, with eight points comprising 2,3,4,5,6,7,8, and 9 on Mohs’ hardness scale, as shown above.
• Two Hardness Plates (of Mohs' hardness of 3.5 and 5.5)
• A 100 grit Grinding Stone to keep the points sharp.
• Rugged and compact molded Plastic Case.
• Hardness Table for 80 common Materials.
• Complete Instructions, customized for Industrial applications.
