Many people know that a diamond will cut, scratch or otherwise mark the surface of any other naturally occurring substance on our planet because of its hardness. Many people do not, however, have any idea how to measure a material’s hardness in an absolute sense and can only compare the hardnesses of two materials against each other.

For folks who want to determine the hardness of a material in a more quantitative sense, a meter definitely comes in handy.

Digital Hardness Meter Specifications:

• Hardness parameter HL, HRC, HRB, HV, HB, HS
• Battery life: 16 hours continuous
• Auto Power Off: 2 Minutes non use
• Display functions: Hardness scale, hardness value, average indicator and average value, impact direction, type of impact device connected, memory reference
• Accuracy: Within ± 0.5% (or HLD=800)
• Memory: 1250 groups
• Overall dimensions: 6.2″ x 1.6″ x 1″ (158 x 41 x 26mm)
• Weight: 4.2 oz (120 g)
• Conforming to ASTM A956
