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. TQC’s Pendulum Hardness Tester is a modular system. The instrument itself can be used for both the König and- Persoz method.
TQC develops and manufactures laboratory and field test equipment for Paint and Coatings. TQC instruments are designed to test or measure properties such as adhesion, coating elasticity, condensation and climate, corrosion, cure profile, drying time, gloss and appearance, hardness, impact-resistance, layer thickness, scrub-resistance, surface pre-treatment, viscosity, washability, and more.
