HST-U300 Ultrasonic Portable Hardness Tester

Application：

Widely used to measure hardness of small forgings, cast material, weld inspection, heat affected zone, Ion-nitrided stamping dies and molds, forms, presses, thin walled parts, bearings, tooth flanks, etc.

l Hardness Test of flange edge and gear root stamping parts, mold, thin plate, face-hardened gear tooth, gear groove and taper part;

l Hardness test of axle and thin-wall pipes and vessels;

l Hardness test of wheels and turbine rotors;

l Hardness test of bit edge;

l Hardness test of welding parts;

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

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

Features:

1. Based on the principle of ultrasonic resonance, the surface of the tested workpiece is minimally damaged. It is suitable for measuring finished workpieces with high surface technology requirements;

2. The measurement speed is fast, and the test results can be output within 1 second; the built-in hardness system conversion function can be converted between the three hardness systems of Brinell (HB), Rockwell (HRC) and Vickers (HV);

3. Adopt 3.5-inch LCD color display, the main interface of the screen directly displays the current measurement value, the cumulative measurement times, maximum value, minimum value, average value, automatic storage of measurement data, measurement time, material, hardness conversion table standard, intuitive and comprehensive display;

4. With a single-point calibration mode, one-point calibration is used for materials with different elastic moduli to eliminate the influence of elastic modulus and improve measurement accuracy;

5. With multi-point calibration mode, it can directly adjust HRC, HRB, HRA, HB, HV, especially suitable for composite materials or new materials without hardness value conversion comparison table, which can be directly calibrated for HRC, HRB, HRA, HB, HV;

6. The 10-point factory calibration mode, through the calibration of 10 Vickers hardness blocks with different hardness values, to ensure the factory accuracy of the instrument;

7. Optional Bluetooth printer can print measurement data;

8. Detecting workpieces of different materials only needs to use test blocks of the same or similar material for adjustment without changing the probe;

9. Comply with DIN 50159-1-2008, ASTM-A1038-2005, JB/T 9377-2010, JJG-654-2013, GBT34205-2017 hardness testing standards.
