Leeb hardness tester needs both verification and calibration. Verification is a necessary step to confirm whether it meets the statutory requirements, while calibration is an important means to ensure the accuracy of measurement. The two complement each other and jointly ensure the reliable use of the Leeb hardness tester.
Difference between verification and calibration
Verification: The process of comprehensive inspection, marking and issuance of verification certificates by legal metrological technical institutions for measuring instruments. It focuses on whether the measuring instrument meets the requirements of national metrological regulations and is legal.
Calibration: The process of comparing the measuring instrument with the standard to determine its indication error. Calibration focuses more on the traceability and accuracy of the value of the measuring instrument and is a means for users to control quality by themselves. 1.
The importance of verification and calibration
Ensure measurement accuracy: Whether it is verification or calibration, the ultimate goal is to ensure the measurement accuracy of the Leeb hardness tester. Through regular verification and calibration, the deviation of the measuring instrument can be discovered and corrected in time to ensure the reliability of the measurement results.
Compliance with regulatory requirements: In some industries or fields, the use of unverified or uncalibrated measuring instruments may violate relevant regulatory requirements. Therefore, verification and calibration of the Leeb hardness tester is also a necessary step to meet regulatory requirements.
Improve equipment life: Regular verification and calibration can also help users understand the use of the Leeb hardness tester, promptly identify potential problems and perform maintenance, thereby extending the service life of the equipment.
Application scenarios of Leeb hardness tester
Leeb hardness tester is widely used in the hardness measurement of various materials such as metals and plastics. It is simple to operate and has high detection efficiency, and is particularly suitable for the detection of workpieces with complex geometric dimensions. In the hardness detection of large, medium and heavy parts, the Leeb hardness tester can also replace other hardness testers for detection, making up for problems such as inappropriate conditions and unsatisfactory environment at the detection site.
