AMT216 Ultrasonic Hardness Tester


AMT216 Ultrasonic Hardness Tester


1. Hardness test of flange edge and gear root stamping parts, mold, thin plate, face-hardened gear tooth, gear groove and taper part

2. Hardness test of axle and thin-wall pipes and vessels

3. Hardness test of wheels and turbine rotors

4. Hardness test of bit edge

5. Hardness test of welding parts

6. Measure the depth of deep hole with certain aperture, concave and convex mark with large radians, and irregular plane

7. Hardness test of most ferrous and nonferrous metals and their alloys in industrial production


1. New appearance design, innovative sculpt, convenient to hold and good craft.

2. 3.5 inches large LCD screen with 320×480 color graphics dot matrix, beautiful font and graphics, rich information and clear display.

3. Full English display, menu-type operation, few keys, simple and convenient to operate.

4. For materials with different elastic modulus, only a simple point calibration is required to adapt to the new material.

5. Provide multi-point calibration function for any hardness standard. For materials without conversion table, users only need to prepare 2 to 10 test samples with different hardness to directly calibrate the hardness (Hardness standard is arbitrary, as long as these 2 to 10 samples have the same standard).

6. High accuracy: ±3%HV, ±3%HB, ±1.5HR (using test stand), according with the test error standard of GB/T-34205, JJF1436 and JB/T9377.

7. Tiny test indentation: smaller than a Leeb hardness tester and requires a high-power microscope to see.

8. High test speed: output test results within 2S.

9. Easy to test on assembly line, compare with Leeb hardness tester.

10. 50 sets of data storage, the data includes time information.

11. 360° test without correction.
