Mash Project Combined UCI and LEEB TKM-459CE Combi

Mash Project Combined UCI and LEEB Hardness Tester
TKM-459CE Combi


The TKM-459CE Combi gives you all the advantages of both UCI and Leeb methods of hardness testing.


  • Intuitive "plug and play" graphic interface
  • Bright color graphic display that allows measurements at low temperatures
  • Hi-Lo Alarm threshold
  • Statistical data processing system
  • Fast calibration of device scales with one or two standard test blocks
  • Memory for readings, recording, and analysis
  • Special material calibration with one or two standard test blocks
  • Fast programming of additional scales using two to ten standard test blocks
  • Wide range of metals and alloys
  • Stable measurements not effected by impact from force and time of pressing the probe to surface
  • Low sensitivity to curvature and roughness of surface
  • Hardness measurement in hard-to-reach areas
  • Wide range of accessories

TKM-459CE Combi Applications:

  • Carbon and structural steels as well as other fine-grained tkm-459ce-applications
  • Hard-surfaced items (cementation, nitride hardening, induction hardening
  • Heat-resistant, corrosion-resistant, stainless steels
  • Non-ferrous metals and alloys (cast iron, aluminum, bronze, brass)
  • Electroplated coating (chrome, copper, nickel, zinc, tin) overlaying
  • Items of complex configuration (gear teeth, shafts, pipes of any diameter, grooves, blind holes)
  • Thin-walled and small-sized items
  • Large items and heavy-duty equipment (pipelines, rails, construction elements)

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 calibrations to basic scales By HRA, HRB, HSD scales and ultimate tensile strength Hardness testing of high-alloy steel 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 more/less than the values, 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 garbage/incorrect measurement
  • Comparison of results of measurements in the series (the comparison charts on the display of the hardness tester)
