LH100D Leeb Hardness Tester

Product description

The LH100D is a pen-type (integrated) Leeb hardness tester designed for fast, non-destructive hardness testing of metal materials on-site or in the lab. It measures 7 hardness scales directly on its OLED display and connects via Bluetooth to a mobile phone or portable printer for real-time data sharing and report printing, storing several thousand measurement sets for later review. The standard D-type impact device covers most general-purpose applications across a wide range of metals.
