JG-119AM Micro Vickers Hardness Tester With Automatic Measuring System

JG-119AM or JG-119HM (HVT-1000A or 1000B)

Equipment Usage:

  • It can be used to determine the Vickers hardness of steel, non-ferrous metals, ceramics, treated layers of metal surface, and the hardness grads of carburized, nitrided and hardened layers of metals. It is also suitable to determine the Vickers hardness of micro and super thin parts.
  • It is useful for a variety of applications: testing very thin materials like foils or measuring the surface of a part, small parts or small areas, measuring individual microstructures, or measuring the depth of case hardening by sectioning a part and making a series of indentations to describe a profile of the change in hardness.



  • Made with a unique and precision design in the field of mechanics, optics and light source. Able to produce a clearer image of indentation and hence a more precise measurement.
  • By means of a 10X objective and a 40X objective and a 10X microscope for measurement.
  • It shows measuring method, the testing force value, the indentation length, hardness value, the dwell time of the testing force, as well as the number of measurement on the LCD screen.
  • During the operation, put in the diagonal length with the keys on the keyboard, and the built-in calculator automatically calculates the hardness value and shows it on the LCD screen.
  • The tester has a threaded interface that can be linked to the digital camera and CCD pickup camera.
  • The light source of the tester is firstly and uniquely adopted cold light source, and hence its life can reach 100000 hours. The user also can select halogen lamp as light source according to their requirement.
  • The CCD image processing system can finish the process automatically: measurement of the diagonal length of indentation, hardness value display, testing data and image saving, etc.
  • It is available to preset the upper and lower limit of hardness value, the testing result can be inspected whether it is qualified automatically.
  • Proceed hardness testing on 20 test points at one time (preset the distance between test points at will), and save the testing results as one group.
  • Converting between various hardness scales and tensile strength.
  • Inquire the saved data and image at any time.
  • Customer may adjust the accuracy of the measured hardness value at any time according to the calibration of Hardness Tester.
  • The measured HV value can be converted to other hardness scales (HB, HR etc.)
  • System provides a rich set of image processing tools for advanced users. The standard tools in the system include adjusting Brightness, Contrast, Gamma, and Histogram Level, and the Sharpen, Smooth, Invert, and Convert to Grey function. On grey scale images, system provides various advanced tools in filtering and finding edges, as well as some standard tools in morphological operations such as Open, Close, Dilation, Erosion, Skeletonize, and Flood Fill etc.
  • System provides the tools to draw and measure common geometric shape such as lines, angles 4-point angles (for missing or hidden vertexes), rectangles, circle, ellipses, and polygons. Note that the measurement assumes the system is calibrated.
  • System allows user manage multiple images in an album which can be saved to and opened from an album file. The images can have the standard geometric shapes and the documents as entered by user as described above.
  • On an image, system provides a document editor to enter/edit documents with contents either in simple plain test format or in advanced HTML format with objects including tabes, list, and images.
  • System can print the image with user specified magnification of it is calibrated.
