86252C Leeb Hardness Tester
Optimized for testing surface-hardened layers and components with low mass or thin profiles
Utilizes Impact Device C
Features dual-coil technology for superior accuracy and repeatability
Built-in orientation sensor enables full-angle measurement
The 86252C is a compact, all-in-one hardness tester designed for accurate measurements on a wide range of metal materials. It features a C-type impact device with low impact force, making it ideal for assessing the hardness of surface-hardened layers and small or thin components. Advanced dual-coil technology ensures high measurement precision and consistency. The integrated orientation sensor in the probe automatically adjusts for different testing angles, providing reliable results regardless of direction. The tester supports five interchangeable hardness scales—Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), and Rockwell (HRC)—removing the need for manual conversions.

FAQ
-
What is the thinnest thickness a durometer can measure and what is the thinnest thickness after coupling?
Leeb hardness tester is only suitable for large and heavy workpieces, small and thin parts must be coupled to a solid support for testing; D-type impact device is measured by the minimum mass of 5kg, the minimum thickness of 25mm, if the weight or thickness does not meet the requirements, must be coupled to a solid support for testing, coupled to the minimum thickness of the measured object is 3mm.
