Overview
The TQC Pendulum hardness tester model SP0501 is an instrument for defining Hardness by the König and Persoz methods described in the ISO 1522 standard. The instrument features a Modular design that easily switches between the two Measuring methods with the push of a button, and is equipped with an automatic electronic counting mechanism and a transparent ventilating cover for easy operation and maintenance.
Features
1. Suitable for Konig swing bar and Persoz swing bar, 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 sample, and once it is at the 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 the principle that the pendulum needle swings differently on different soft Hardness surfaces. The softer the surface, the faster the swing weakens, and vice versa. Hardness is expressed by the damping time of the oscillation of the pendulum rod on the sample. The principle of the König and Persoz pendulum rods is the same but the swing period, swing and size of the pendulum needle are different.
Applications
Laboratory, coatings, paints industry, automotive industry
Standards
ISO 1522 (2005)、NBN T22-105、BS3900 E5
Steps
1. Level the instrument and place the level indicator above the test panel.
2. Place the correct swing bar (König or Persoz).
3. Switch the Measuring method through the button.
4. Stepping motor automatically positions the swing rod.
5. The electromagnetic system releases the swing rod to start testing.
6. The end of the test is indicated by visual and acoustic signals.
Notice
• The instrument does not need to be further calibrated after leveling.
• Make sure the water level is located on the specimen, not on the instrument base.
• When using a transparent ventilating cover supported by a gas spring, pay attention to safe operation.
• The swing rod needs to be booked separately to ensure that the correct type is selected.
• Avoid interfering with the automatic counting mechanism during testing.
