HUH-6M Handheld Manual probe Brinell Rockwell Vickers Ultrasonic
Hardness Tester◣Product overviewThere are many types of hardness testing methods,commonly used
methods include HB, HRC, HV, HL, etc. But all these methods have
boundness. The test force of HB and HRC is strong, so the
indentation is big, and the damage to the surface is obvious. HV is
tested by optical method, which needs very professional and
technical personnel to operate, and cannot directly test large
workpiece. And our ultrasonic hardness tester HUH-6M uses
ultrasonic contact impedance method to compare and test patterns,
this new method brings advantages of high precision, fast speed,
portable, easy operation, etc.◣Technical parameters:Model | HUH-6M | Standard | DIN50159-1-2008; ASTM-A1038-2005; JB/T 9377-2010; JJG-654-2013;

◣ApplicationsHardness test of flange edge and gear root stamping parts, mold,
thin plate, face-hardened gear tooth, gear groove and taper partHardness test of axle and thin-wall pipes and vesselsHardness test of wheels and turbine rotorsHardness test of bit edgeHardness test of welding partsMeasure the depth of deep hole with certain aperture, concave and
convex mark with large radians, and irregular planeHardness test of most ferrous and nonferrous metals and their
alloys in industrial production
◣Functional characteristicsNew appearance design, innovative sculpt, convenient to hold and
good craft.3.5 inches large LCD screen with 320×480 color graphics dot matrix,
beautiful font and graphics, rich information and clear display.Full English display, menu-type operation, few keys, simple and
convenient to operate.For materials with different elastic modulus, only a simple point
calibration is required to adapt to the new material.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).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.Tiny test indentation - smaller than a Leeb hardness tester and
requires a high-power microscope to see.High test speed -- output test results within 2S.Easy to test on assembly line -- compare with Leeb hardness tester.50 sets of data storage -- the data includes time information.360° test without correction.
