LH100DL Leeb Hardness Tester

Product description

The LH100DL is a pen-type (integrated) Leeb hardness tester with an extended-reach DL impact device, designed for fast, non-destructive hardness testing inside deep holes and blind holes that standard probes cannot reach. It measures 6 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.
