Elcometer 3045 Persoz & König Pendulum Hardness Tester

GENEQ > Materials Testing> Hardness Testers

Product Description

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.

Sturdy and Robust design ensures consistent results
Internal storage for the calibration tile and pendulum
Fully automatic test - position the sample, close the door and press start
Automated Calibration ensures pendulum operates precisely within specified limits
Batch memory stores all test data for output to a PC via the supplied ElcoMaster 2.0 software
Adjustable feet and bubble indicator ensures test is level
Multilingual menu driven operation
Rigid Perspex door provides easy access for sample positioning

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 12° to 4°, whereas the König measures from 6° to 3°.

Hardness Testing

Hardness can be defined as a material’s resistance to permanent deformation.
In the coatings industry, hardness measurement can be used to determine the resistance of the coating to scratching from general wear and tear and also if a coating is fully cured.

The term “Hardness” is used to refer to different properties of material, specifically resistance to scratch and wear and resistance to penetration.

Depending on the requirements, there are various methods for testing hardness. Some are dedicated to characterise coatings and others are more suitable for testing bulk materials such as metals, plastics, rubber or elastomers.

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, including:

Automatic 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.
Fully Automated Test - once the sample and the pendulum are in position and the door closed, pressing the Start button:
- Lifts the Sample on to the balls of the selected pendulum
- Moves the pendulum to the correct start position
- Automatically releases the pendulum and counts and stores the number of oscillations into the batch memory
- Returns the sample and pendulum to the start position ready for the next test in the set of three
Output to the PC - each set of results can be stored and transferred to the PC for further analysis and report generation via the RS232 connection
