The 10 N sensor measures a roughness of less than 3.2 µm and the one with 98 N measures a roughness of less than 15 µm. Hardness testing is absolutely critical in many industries and phases of manufacturing. Detecting defects during this process can save thousands of dollars and a lot of headaches later due to product or structural failure. Instead, you want to use a non-destructive testing method, like Ultra Sonic Hardness testing.

Motorized probe systems are used for testing of very thin coatings and platings or surfaces with a high-polish finish. “Dynamic Impact”is based on theLeebprinciple of hardness developed by Dietmar Leeb in the 1970’s. The speed of both the initial thrust and the rebound is measured in a non-contact mode.
ASTM G65 measures the resistance of metallic materials to abrasion using the dry sand/rubber wheel apparatus. The quality, durability, and toughness of the sample are determined using this test. Metallic materials are ranked in their resistance to scratching abrasion under a controlled environment. ASTM E572 test method covers the analysis of stainless and alloy steels by Wavelength Dispersive X-ray Fluorescence Spectrometry .

The instrument consists of a 64-element tactile sensor array designed to visualize haptic information within the breast. It was demonstrated in both basic and clinical studies that the hardness of breast cancer lesions larger than 10mm located at depths less than 20mm could be detected using this novel haptic probe. We expect that the proposed instrument will be useful for the detection and follow-up of treatment and to predict the response to neoadjuvant chemotherapy. This test method covers the determination of comparative hardness values by applying the Ultrasonic Contact Impedance Method . Micro Vickers/Knoop hardness benchtop testers are cost-effective options in Vickers hardness applications. Testing is per-formed on extremely thin/small workpieces and is often used for checking the hardness of layers, platings and coatings on small parts in a laboratory environment.
