Pendulum Hardness Tester - Konig - Persoz

Conforms to ASTM D4366 and ISO 1522.

The Pendulum Hardness tester is very precise measurement of hardness using either a Konig or Persoz pendulum.

The Pendulum Hardness Tester - Konig - Persoz is a simple laboratory measuring instrument for hardness measurements in accordance with the König and Persoz methods implemented into the system.

Features of the Pendulum Hardness Tester - Konig - Persoz

  • Automatic counter with acoustic signal when the deflection is below 3° (König) or 4° (Persoz) respectively
  • Registration of pendulum deflection by means of 2 light barriers
  • Digital counter
  • Changeable from König to Persoz by means of a third light barrier
  • Selector switch for display in seconds or number of oscillations
