Ultrasonic Hardness Gauge For Measuring Groove Tooth Flanks 

With Test Force 49N



Characteristics:

  • Directly test Vickers hardness value of workpiece, and there is no need to convert like Leeb or Shore hardness tester. The conversion error is eliminated.
  • High test speed -- output test results within seconds
  • Standard Vickers indentation, tiny indentation, little damage to the workpiece
  • The test results are related to the elastic constants of the workpiece. New workpiece needs to be calibrated according to the elastic constants.
  • Small volume, light weight and easy to carry.
  • Easy to test on assembly line.
  • It can be used for testing on site and testing large workpiece and can be used to make hardness measurements on positions difficult to access, such as tooth flanks or roots of gears.
  • Only measuring the hardness condition of the surface contacted
  • The development of microcontroller technology makes it easy to calibrate workpiece with different elastic constants.

Probe Specification:

  • Probe:5kgf manual probe

  • Diameter:22mm
  • Length:150mm
  • Resonating rod diameter:2.4mm
  • Maximum roughness of test surface:Ra<10μm
  • Minimum workpiece weight:0.3kg
  • Minimum workpiece thickness:2mm
  • Application:Groove, tooth flanks, roots of gears

Technical Specification:

  • Main hardness scale: HV ;Convertible hardness scale: HRC, HRA, HRB, HBW
  • In multi-points calibration mode, any hardness scales can be chosen.
  • Testing range: HV50~1599, HRC20~68, HB85~650
  • Test direction:Support 360° test, as long as the angle between the indenter and the surface doesn’t exceed 90° ± 3°.
  • Battery: 3.6V, 3000mAh lithium battery
  • Endurance: 10 hours
  • Test data can be exported to computer terminal.

  • Norms: GB/T 34205-2017; DIN 50159-1-2008; ASTM-A1038-2005; JB/T 9377-2010; JJF 1436-2013.
  • High accuracy----±4%HV, ±4%HB, ±1.5HR.
  • Tiny test indentation---- requires a high-power microscope to see.
  • Little damage to the workpiece.
  • High test speed----output test results in 1s at the soonest.
  • New appearance design, innovative sculpt, convenient to hold and good craft.
  • Full English display, menu-type operation, few keys, simple and convenient to operate.
  • 3.5 inches large LCD screen with 320×480 color graphics dot matrix, beautiful font and graphics, rich information and clear display.
  • Directly display the current measured value, cumulative measured value, maximum value, minimum value, average value and conversion value.
  • 50 sets of data storage.
  • Simple calibration----5 sets of one-block calibration data, 1 set of default calibration data and 5 sets of multi-blockss calibration data can be stored in the host.
  • For materials with different elastic constants, just an one-block calibration is required to adapt to the new material.
  • For unknown material or material without conversion table, the hardness scale can be arbitrarily selected for multi-points calibration to eliminate the systematic error brought by the conversion table.
  • Easy to test on assembly line.

Application:

  • Hardness test of flange edge and gear root stamping parts, mold, thin plate, face-hardened gear tooth, gear groove and taper part
  • Hardness test of axle and thin-wall pipes and vessels
  • Hardness test of wheels and turbine rotors
  • Hardness test of bit edge
  • Hardness test of welding parts
  • Measure the depth of deep hole with certain aperture, concave and convex with large radians, and irregular plane
  • Hardness test of most ferrous and nonferrous metals and their alloys in industrial production
  • Hardness test of thin coatings
  • etc.
  • Please note that the application scenarios are different according to different probes.
