Overview
The TQC Pendulum hardness tester (model SP0500) is a Modular system that makes it easy to define Hardness by the König and/or Persoz methods described in ISO 1522. The instrument has a simple menu-driven interface and a slow dial. The automatic electronic counting mechanism is not affected by reflections in the surrounding area. The water level is located on the specimen rather than the instrument base. No further calibration is required after the instrument is leveled.
Features
1. Suitable for Konig swing rod and Persoz swing rod, the instrument switches the test method with one click.
2. Precision electronic automatic counter, accurate counting, not affected by the reflection of the surrounding environment.
3. Push button, easy to operate.
4. A transparent housing supported by air pressure springs makes it easy to observe and maintain.
5. The level indicator is located above the test template, and once it is level, it does not need to be calibrated.
6. Provide audio and visual information when performing tests.
7. Adjust the horizontal foot, which is convenient and sturdy.
8. Glass plate and swing rod storage are integrated with the equipment.
9. The stepper motor automatically positions the swing rod, and automatically releases the swing rod through the electromagnetic system to eliminate manual misoperation.
10. Menu navigation Easily calibrate Konig and Persoz swingers.
Principle
The Pendulum hardness tester is designed based on different principles of the swing of the pendulum on different soft Hardness surfaces. The softer the surface, the faster the swing, and vice versa. The principle of the two pendulum rods (Konig and Persoz) is the same, but the swing period, swing amplitude and size of the pendulum are different. Hardness is expressed by the damping time of the pendulum oscillating on the sample.
Applications
Laboratory, coatings, paints industry, automotive industry
Standards
ISO 1522 (2005)、NBN T22-105、BS3900 E5
Steps
1. Place the correct swing bar.
2. Switch between Konig and Persoz Measuring methods via the button.
3. Stepper motor automatically positions the swing rod.
4. The electromagnetic system releases the swing rod.
5. The end of the test is indicated by visual and acoustic signals.
Notice
• The instrument does not need to be further calibrated after leveling.
• The swing rod should be booked separately.
• Basic equipment is available in 110VAC/50/60Hz and 230VAC/50Hz models.
• Make sure the level indicator is level before use.
