Consisting of a pendulum which is free to swing on two balls resting on a coated test panel, these pendulum hardness testers are based on the principle that the amplitude of the pendulum's oscillation decreases more slowly when supported on a harder surface and reduces faster on a softer surface.

The hardness of any given coating is given by the number of oscillations within the specified limits of amplitude. The Persoz test measures the time taken for the amplitude of oscillations to decrease from 12º to 4º, whereas the König measures from 6º to 3º.


The Elcometer 3045 Pendulum Hardness Tester is equipped with a number of unique features designed specifically to maximise repeatability and reproducibility of the pendulum hardness test method.

  • Sturdy and robust design ensures consistent results
  • Fully automatic test - position the sample, close the door and press start
  • Batch memory stores all test data for output to a PC via the supplied ElcoMaster™ Software
  • Automated calibration
    • The user places the supplied glass calibration tile in place of the sample, positions the appropriate pendulum on the positioning pins and closes the door. The Elcometer 3045 then performs a full calibration routine and automatically adjusts the unit to meet the specified standards.
  • Adjustable feet and bubble indicator ensures test is level
  • Multilingual menu driven operation
  • Rigid perspex door provides easy access for sample positioning
  • Internal storage for the calibration tile and pendulum
