MASH Project TKM-459CE Leeb

The TKM-359CE Leeb Method Hardness Tester is made for fast and simple hardness measurements in manufacturing, and field conditions.

Features:

  • Easy to use
  • Ruggedly builts
  • Intuitive graphic interface
  • Bright color graphic display that allows measurements at below freezing temperatures and it stays bright in any lighting
  • Unique system for statistical data processing and averaging of readings
  • Special calibration for non-standard materials with one or two known hardness references
  • Memory for recorded readings and their analysis
  • Fast programming of additional scales with one or two standard test blocks
  • Stable measurements independent from force and time of pressing the probe to surface
  • Low sensitivity to curvature and roughness of surface
  • Monitoring of hardness change along surface
  • Control of "volumetric" hardness
  • Wide range of metals and alloys

TKM-359CE Leeb Tester Applications:

leeb applications
  • All basic types of metals and alloys without
    additional calibrations (structural, tool, heat-proof, non-corrosive steels, and alloys, as well as alloys of nonferrous metals, cast-iron, aluminum, bronze, brass)
  • Items with surface hardening and induction hardening
  • Items of complicated configuration
  • Heavy and big items with rough surface

    Testing Requirements:

    • Items heavier than 11 lb. (5 kg) and thicker than 0.24” (6 mm) need no additional preparation
    • Hard items (ex. tubes) with expected hardness from 90 to 250 HB and thicker than 0.16” (4 mm) need no additional preparation
    • Other items should be fixed on a support plate by fixing paste

    Hardness Tester Modes
    Measurement Mode Readings Using
    By basic scales Basic hardness units (HRC, HB, HV) Hardness testing of the bulk of products
    By additional calibration to basic scales By HRA, HRB, HSD scales and ultimate tensile strength Hardness testing of high-alloy steels, special cast iron and nonferrous metals
    By additional scales Scales are programmed by the user Special problem solving


    The parameters of the statistical processing of measurements

    • Maximum, minimum, mean value, standard deviation from the mean
    • The average deviation from the values set by a user, results are plus or minus standard value, the maximum deviation in the large/smaller side of the value
    • Number of results outside the upper/lower limit of range (user specified), maximum deviation from the upper/lower border
    • Automatic rejection of bad or incorrect measurements
    • Comparison measurement results of a series of measurements (the comparison charts on the display of the hardness tester)
