LH100C Leeb Hardness Tester

Product description

The LH100C is a pen-type (integrated) Leeb hardness tester with a low impact-energy C-type impact device, designed for fast, non-destructive hardness testing of small, thin, or lightweight workpieces that could be damaged or displaced by standard impact devices. It measures 5 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.
