Pendulum Hardness Test TQC



Pendulum Hardness Test TQC

TQC Pendulum Hardness Test has a lot of unique features that ease defining hardness by the Konig or Persoz method as described in ISO 1522. Both methods work on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness.

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 Pendulum are available. Both are based upon the same principle but differ in respect of dimensions, period and amplitude of oscillation.

The instrument has an easy menu-driven interface with jog dial. The automated electronic counting mechanism is not affected by reflections from the surrounding area. The water-level is located on the test specimen, rather than on the instrument’s base. Once the instrument is leveled further calibration is not required. The gas-spring supported transparent draft cover allows easy access to all parts of the instrument.

TQC’s Pendulum Hardness Tester is a modular system.

The instrument itself can be used for both the König and- Persoz method. Both pendulums should be ordered separately. After placing the correct pendulum, switching between the two measuring methods only takes a push of a button. The Pendulum is positioned fully automatically by means of a

stepper motor. Also the release of the Pendulum is automated through electro-magnetic system. The end of a test is indicated by a visual and acoustic signal.

The TQC Pendulum Hardness Tester base device is available as a 110VAC / 50/60Hz and a 230VAC / 50Hz model.
