Product Description
G Probe Leeb Hardness Tester Impact Device

Professional G-type impact device for Leeb hardness testing with 90mJ impact energy, designed for heavy industrial applications.

Key Features
  • Enlarged 5mm test tip for improved contact
  • High impact energy of 90mJ (approximately 9 times that of type D)
  • Low demands on measuring surface finish
  • Specifically designed for Brinell range measurements (max. 650 HB)
  • Ideal for solid components including heavy castings and forgings
Working Principle

The device operates by impacting the sample surface with a calibrated mass under specific test force. It measures impact and rebound speeds at 1mm distance using electromagnetic principles, where induced voltage is proportional to velocity.
