Description
Pendulum Hardness Test TQC
TQC Pendulum Hardness Test has a lot of unique features that ease defining hardness by the Konig or Persoz method as described in ISO 1522. The both of methods work on the principle that the damping time of a pendulum oscillating on a sample indicates the hardness.
The pendulum hardness test is based on the principle that the amplitude of oscillation of a pendulum touching a surface decreases more rapidly the softer the surface.
Two types of Pendulum are available. Both are based upon the same principle but differ in respect of dimensions, period and amplitude of oscillation.
The first this instrument has an easy menu-driven interface with jog dial. The automatic electronic counting mechanism is not affective by reflections from the surrounding area. The water-level is located on the test specimen, rather than on the instrument’s base. Once the instrument is leveled further calibration is not required. The gas-spring supported transparent draft cover allows easy access to all parts of the instrument.
TQC’s Pendulum Hardness Tester is a modular system.
The instrument itself can be use for both the König and- Persoz method. Both pendulums should be orders separately. After placing the correct pendulum, switching between the two measuring methods only takes a push of a button. The Pendulum is position fully automatically by means of a stepper motor. Also the release of the Pendulum is automatic through electro-magnetic system. The end of a test is indicated by a visual and acoustic signal.
The TQC Pendulum Hardness Tester base device is available as a 110VAC / 50/60Hz and also a 230VAC / 50Hz model.
Pendulum Hardness machine recommended use in field Laboratory, Coating Industry, Paint Industry, and also Automotive Industry.
Available electric power 110VAC / 50/60Hz, and 230VAC / 50Hz.
Hardness testing with an accurate pendulum tester
From our specialist brand TQC Sheen, this flexible and easy to use pendulum tester is a reliable instrument for hardness testing on a wide range of paints and coatings. It offers many 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.
Why choose the TQC Sheen Pendulum Hardness Tester?
Ergonomic and robust design: Built for durability and ease of use, the TQC Sheen Pendulum Hardness Tester is a dependable solution for laboratory testing. Its intuitive calibration menu simplifies setup and ensures accurate results for both König and Persoz methods.
Reduce operator bias: To enhance repeatability and reduce human error, the tester features automated pendulum positioning via a precision stepper motor. The pendulum release is also fully automatic using an electromagnetic system, ensuring consistent and unbiased test execution.
Intuitive LED Feedback System: The integrated LED status indicator provides clear, real-time feedback using a colored light system.
For calibrations, the instrument uses simple traffic-light colored light feedback:
- Green light: Test has passed
- Red light: Test has failed
- Amber light: Test is in progress
This visual feedback helps operators quickly interpret results and maintain efficient workflows.
With the LED light strip, operators can also customize the light intensity and color to suit their requirements. There are pre-set six colors to choose from or you can chose the RGB input, as well as adjust the intensity of the light.
Two hardness testing methods in one
The TQC Sheen Pendulum Hardness Tester is a modular testing system, which allows you to carry out König and/or Persoz methods by attaching the appropriate pendulum. Pendulums can be orderes separately. Once the correct pendulum has been attached, you can switch between methods at the push of a button. For both, the amount of time it takes for the pendulum to decrease its swinging angle is use to determine the hardness of the surface material being test.
König hardness testing
The König pendulum consists of an open framework connected by a cross-bar with two balls attached to the underface. The lower end of the framework is formed into a pointer and a weight sliding on a vertical rod and also attached to the cross-bar is used to counterpoise the pendulum. The damping time, in seconds, for the oscillation amplitude of the König pendulum to decrease from 6°to 3° is measured.
Persoz hardness testing
The Persoz pendulum is made from an open framework with an upper cross-bar that has two stainless steel balls inset to form a fulcrum. It also has a lower cross-bar that forms the pointer. The damping time, in seconds, for the oscillation amplitude of the Persoz pendulum to decrease from 12°to 4° is measure.
Meeting hardness testing standards
Meeting the testing standards and international regulations associated with your testing method is always an essential. That’s why this pendulum tester is compliant with ISO 1522, the global standard for carrying out a pendulum damping test on paints, varnishes and also coatings. Additionally, the TQC Sheen Pendulum Hardness Tester is also suitable for testing to ASTM D4355 for testing hardness of organic coatings.
Seamless Data Extraction via USB
Capturing and also transferring your test data is effortless with the TQC Sheen Pendulum Hardness Tester. Equipped with a conveniently located USB port, the instrument allows users to quickly export hardness test results directly to a computer – streamlining data handling and also improving workflow efficiency.
