Pendulum Hardness Tester

The Pendulum Hardness Tester is a precision testing system used to measure the surface hardness and drying behavior of paints, varnishes, and coating materials in accordance with ISO 1522. Supporting both the König and Persoz methods, this test technique reliably determines the mechanical resistance of coating films by analyzing the damping motion occurring on the coated surface.

It is an ideal solution for paint manufacturers, automotive coating applicators, R&D laboratories, and quality control departments. Pendulum hardness testing plays a key role in product development, process optimization, and the standardization of product quality. Thanks to its high measurement accuracy and repeatable test results, it enables an objective evaluation of coating performance.
Standards: ISO 1522, ASTM D4366; Superseded standards: DIN 53157, NBN T22-105, BS 3900-E5, NF T30-016

Hardness Testing with an Accurate Pendulum Tester

This flexible and easy-to-use pendulum tester is a reliable solution for hardness testing across a wide range of inks and coatings. It offers many unique features that simplify hardness determination using the König and/or Persoz methods as described in ISO 1522.

Both methods are based on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness of the coating.

Why Choose the TQC Sheen Pendulum Hardness Tester?

Ergonomic and robust design:

Developed for durability and ease of use. The intuitive calibration menu simplifies setup and ensures accurate results for both König and Persoz methods.

Reduced operator bias:

To enhance repeatability and minimize human error, the tester features automatic pendulum positioning via a precision stepper motor. The fully automated electromagnetic pendulum release mechanism ensures consistent and unbiased test execution.

Intuitive LED Feedback System:

The integrated LED status indicator provides clear, real-time feedback through a color-coded light system. During calibration, it operates like a traffic light:

Green light: Test passed
Red light: Test failed
Yellow light: Test in progress

This visual feedback allows operators to interpret results quickly and maintain efficient workflows. With the LED light strip, users can also customize light intensity and color according to their needs. Six preset colors or RGB input options are available, along with adjustable light intensity.
