Universal hardness tester TH-172

Quick and easy

The hardness testers of the TH-series are especially suitable for quick and easy hardness measurements.

They are applicable with almost all hardness measurements on ferrous and non- ferrous metals. Costumers of the product include the power industry, petrochemical industry, apparatus-, automotive- and mechanical-engineering, quality control, steelworks and many more.

Features and equipment

  • For fast, on site hardness testing
  • Integrated Impact device C
  • All hardness units: HL (Leeb), HB (Brinell), HRB (Rockwell B), HRC (Rockwell C), HV (Vickers), HS (Shore D)
  • Measuring range: 230-960 HLC / 80-996 HV on steel
  • Storage capacity up to 270 readings divisible into 9 blocks
  • PC data transfer via USB to MS Hyper terminal for storing and printing
  • Adjustable display illumination
  • Accuracy: up to ± 12 HLD (± 0.5 %)
  • Automatic shutdown
  • Automatic impact direction detection
  • Deletion of data automatically or manually
  • Limit setting (min. And max . Adjustable with arrow indicate exceeded)
  • Software calibration with test block

Application

The impact device type C has a reduced impact energy.
This is approximately ¼ of the impact energy of the percussion device type D. This makes the TH-172 particularly suitable for surface-hardened working parts, casing, thin coated or impact sensitive components, thin walls (small indentation depths), also fixtures, dies, molds, large parts, axles, knuckle, frames etc. Furthermore, the device is also often used for material identification and for error checking in pressure vessels and steam turbines.

  • Production of metal and rubber components
  • Mechanical engineering
  • Research and development
  • Solid state physics
