Description
The TQC Pendulum Hardness Tester has a lot of unique features that ease defining hardness by the König and/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 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.

How It Works
- Prepare the coated test panel according to the required test method and curing procedure.
- Place the test panel flat on the instrument’s sample support plate.
- Adjust the pendulum arm to its initial starting position.
- Release the pendulum and allow it to swing over the coated surface.
- The pendulum’s oscillation amplitude will decrease as it interacts with the film.
- The instrument measures the number of oscillations or energy lost, which correlates to surface hardness.
- The end of a test is indicated by a visual and acoustic signal.
