Twin-Pendulum Bar Hardness Tester

The double pendulum hardness tester measures the hardness of coatings by determining the decay time of free oscillation of two articulated pendulum rods. The steel ball at the end of the pendulum rod contacts the coating surface, and greater oscillation resistance results in faster decay. It is used to detect the curing degree of coatings and plastic surfaces, in accordance with international standard testing methods.
Selection
When selecting, consider the hardness range of the material to be tested. For conventional coatings, use the König pendulum; for soft materials, use the Persoz pendulum. Verify that the instrument complies with ISO and ASTM standards. Check whether the pendulum period falls within the standard value ±0.5s. Confirm the accuracy of the leveling adjustment device. Validate the steel ball specifications and surface roughness.
