The AH-200-T is a portable hardness tester based on the LEEB rebound principle for HLD testing. The principle consists of arming a spring which is released by a thumb pulse, propelling the indenter over the sample. The hardness is determined by the speed of the rebound. Although reliable and accurate, this type of hardness tester has a fairly limited field of application, since rebound technology is only suitable for testing solid parts with a thickness of 40 mm or more. For thicknesses of less than 40 mm, a penetration test is preferable, as with the e-COMPUTEST, for example.

Principle of rebound durometer testing :

• Impact system with separate probe
• Direct reading in Rockwell – Brinell – Vickers – Shore and LEEB on digital window
• Lightweight and easy to use
• Measures in all positions.0° 45° 90° 135° 180° (can be set before testing)
• Power supply: 2 x AAA 1.5V batteries
