Some customers ask if ultrasonic hardness testers can replace desktop hardness testers? Of course not!

Ultrasonic hardness tester is ultimately a comparative hardness tester, and calibration is required before measuring a new material each time. The source of calibration data is a desktop hardness tester. Without a calibration data source for desktop hardness testers, the measurement accuracy of ultrasonic hardness testers cannot be discussed.

Of course, using it for measurement can increase the efficiency of measurement by tens of times, reduce the labor intensity of quality control personnel, and improve measurement efficiency and accuracy. And it can measure the hardness of coatings, hardened layers, and HAZ on large workpieces without indentation, and also solve the problem of inaccurate measurement of hardness of small thin samples by other portable hardness testers. So each has its own strengths and complements each other.
