There are various common hardness testing methods (HB, HRC, HV, HL, etc.), but all have limitations: HB/HRC use high test force, causing large indentations and obvious surface damage; HV relies on optical operation, requiring professional technicians and unable to test large workpieces. Our ultrasonic hardness tester adopts the ultrasonic contact impedance method, offering advantages like high precision, fast speed, portability, and easy operation.

Standard:DIN50159-1-2008; ASTM-A1038-2015;
Range:HV50-1599, HRC20-76, HB76-618, HRB41-100, HRB41-100, HRA61-85.6, Mpa255-2180
Test Error:HRC: ± 2HRC; HB: ± 3%HB; HV: ± 3%HV
Working Temperature:-20℃~50℃
Working Humidity:<=85%
Probe test Force:2kgf(optional 0.5kgf, 1kgf, 5kgf, 10kgf)
Dispaly:3.5 inches large LCD screen with 320×480 color graphics dot matrix, beautiful font and graphics, rich information and clear display.
Calibration: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)
Accuracy:-- ±3 %HV, ± 3%HB, ± 1.5HR (using test stand), according with the test error standard of GB/T-34205, JJF1436 and JB/T9377.
Indentation:smaller than a Leeb hardness tester and requires a high-power microscope to see.
Test Speed: output test results within 2S.
Storage:50 sets of data storage
