Pendulum Hardness Tester Konig/Persoz

The pendulum hardness test is based on the principle that the amplitude of oscillation of a pendulum touching a surface decreases more rapidly the softer the surface. Two types of pendulums are available. Both are based upon the same principle but differ in respect of dimensions, period and amplitude of oscillation.

Features

  • The Pendulum hardness tester is suitable for both Persoz and König Tests. Switching between the methods only takes a push of a button.
  • Easy menu-driven single button interface
  • The automated electronic counting mechanism is not affected by reflections from the surrounding area.
  • The gas-spring supported transparent draft cover allows easy access to all parts.
  • The spirit level is located on the test specimen. Once leveled further calibration is not required.
  • Design ‘Solid Supports’ to level the instrument.
  • The pendulum is positioned fully automatically by means of a stepper motor. The release of the pendulum is automated through an electro-magnetic system. This eliminates human errors.
  • Visual and acoustic signal when test is performed.Integrated storage of glass plate and pendulum.
  • Menu-driven calibration menu eases both Persoz and König calibration
