Portable Digital Rebound Hardness Tester Gauge

This digital hardness tester measures the hardness of sample materials in terms of Hardness Leeb (HL). It is a highly portable yet powerful and versatile tool for testing various metallic materials, including steel, cast steel, cold work tool steel, stainless steel, grey cast iron, nodular cast iron, cast aluminum, brass, bronze, and copper alloys. With high accuracy, it is suitable for use under tough working conditions. The tester can perform tests at any angle, even upside down. Additionally, a thermal mini-printer can be attached for fast on-site printing of results.
