Best Application: Pendulum Hardness Tester on color

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

Applications

Simple laboratory measuring instrument for hardness measurements in accordance with the König and Persoz methods.

  • 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
