FAQ's of TESTMANN TH-450 High Precision Colour Screen Portable Hardness Tester (Leeb D):

Q: How does the TESTMANN TH-450 perform hardness testing on metals?

A: The TH-450 uses the Leeb rebound principle, where a standardized impact device (Leeb D) strikes the test surface and measures the rebound velocity. This method accurately determines the hardness of metals and displays the result instantly on the color screen.

Q: What types of metal can I test with this device, and what hardness scales are supported?

A: You can use the TH-450 to test a wide variety of metals. It measures in the Leeb Hardness (HLD) scale and offers automatic conversions to Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Vickers (HV), and Shore (HS) for broad application support.

Q: When should I perform calibration on the tester, and is user calibration possible?

A: Calibration is recommended when the tester is newly set up, after impact device replacement, or if test results seem inconsistent. The TH-450 includes a user calibration function, allowing in-field adjustment to maintain accuracy.

Q: Where can I review or export my hardness test data?

A: Test data can be reviewed directly on the tester's color display. For further analysis or recordkeeping, data can be exported to a PC via the USB interface, supporting streamlined reporting and documentation.

Q: How is the device powered, and how long does the battery last during operation?

A: The TH-450 is powered by a rechargeable lithium-ion battery, supporting up to 150 hours of continuous use with the backlight off. Charging is conveniently done via USB, ensuring reliable operation during extended work sessions.

Q: What specimen sizes are suitable for testing with the TH-450?

A: The minimum specimen requirement is 2 kg in weight (on a solid support) and 3 mm in thickness. These guidelines help ensure measurement accuracy when testing workpieces directly.

Q: What are the key benefits of using the TH-450 for metal hardness testing?

A: The TH-450 delivers high-precision, immediate hardness results, flexible portability, extensive memory storage, multi-language menus, and efficient data management. Its sturdy build and long battery life make it ideal for both laboratory and field inspections.
