Frequently Asked Questions about Hardness Testers in 2022

1. Question: What kind of Hardness Tester is used to measure the hardness of ash wood?

     Answer: Hello! Shore Hardness Tester can be used.

2. Question: Which Hardness Tester is suitable for measuring carrots?

     Answer: Hello! Find one that suits you, NBC-15 Fruit Hardness Tester can test it.

3. Question: Can the Shore Hardness Tester be used for rubber and plastic?

     Answer: Hello! Yes, the Hardness Tester has multiple models to choose from depending on the hardness.

4. Question: Can I test the solder-proof ink PCB board when I buy a Hardness Tester? Trolley-type ink Hardness Tester

     Answer: Hello! The pencil Hardness Tester is generally made of ink on tinplate, and then tested. Not tested directly on the PCB board.

5. Question: How does the pencil Hardness Tester determine which value is the coating hardness tested?

     Answer: Hello, the test hardness value of the pencil Hardness Tester is the former of the pen that just fails the test. If H has no scratches and 2H has scratches, the hardness of the test piece is H.

6. Question: We require users to use a pendulum Hardness Tester for 150 seconds, and we use a pencil Hardness Tester. Can the two be converted?

     Answer: Hello! It cannot be converted, and the standard basis is completely different.

7. Question: Does the pencil Hardness Tester need to be calibrated?

     Answer: Hello! In theory all instruments need to be calibrated. However, based on the design principle of the pencil Hardness Tester, the calibration only exists in the calibration of its approved weight. The pencil Hardness Tester is made of high-grade metal, which is unlikely to cause weight changes, so it is recommended that no calibration is required.

8. Question: What is the difference between D-type Shore Hardness Tester and A-type?

     Answer: Hello! Hello, the D-type Shore durometer is used to measure materials with higher hardness, such as hard plastics, hard rubber, etc., while the A-type Shore durometer measures plastics and synthetic rubbers with lower hardness values.

9. Q: How to calibrate the Shore Hardness Tester?

     Answer: Hello, there are two calibration methods: 1. Zero point calibration: After turning on the machine, the Shore Hardness Tester is in working condition, the indenter stretches out to the maximum at this time, and the hardness value on the screen should display zero. 2. Non-zero point calibration: Put the bottom of the Shore Hardness Tester in full contact with the flat glass plate, so that the extension length of the indenter is zero, and the hardness value displayed on the screen should be 100.

10. Question: Does the Leeb Hardness Tester test the hardness of the material itself? Or measure the hardness of a coating on a material?

       Answer: Hello, it is to measure the hardness of metal materials. If it is to test the hardness of the coating, an ultrasonic Hardness Tester must be used.
