Now your capabilities in non-destructive hardness testing of diff erent metal items are almost unlimited.

Combined Hardness tester TKM‑459CE combi - portable precision device with brand-new soſt ware.

Device is intended for non-destructive testing of production quality in metallurgy, mechanical engineering, aircraft, shipbuilding, atomic industry, oil and gas industry.

Applying TKM-459CE combi you receive all advantages of UCI and Leeb methods of metals and alloys hardness control.

TKM-459CE combi controls hardness of following:

  • Carbon and structural steels as well as other fine-grained materials
  • Hard-surfaced items (cementation, nitride hardening, high frequency current hardening)
  • Heat-resistant, corrosion-resistant, stainless steels
  • Non-ferrous metals and alloys (cast iron, aluminium, 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 (gas pipelines, rails, construction elements)

Exploitation advantages

- Wide range of metals and alloys.
- Stable measurements with no 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 (position of probe has no impact on the results of measurement).
- Wide range of accessories.

Features of TKM-459CE combi

1. Impact-, dust- and water-proof housing.
2. Intuitive “plug and play” graphic interface.
3. Bright color display allows to make measurements at below zero temperature.
4. Signalization about exceeding of prescribed measurement threshold.
5. Unique statistical data processing system.
6. Fast calibration of device scales with one or two standard test blocks.
7. Flexible device memory for readings recording and analysis.
8. Programming of additional calibrations for scales of hardness tester with one or two standard test blocks.
9. Fast programming of additional scales with two to ten standard test blocks.

Hardness testers 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 steels, special cast iron and nonferrous metals
By additional scales  Scales are programmed by the user Special problems 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 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 garbage results, incorrect measurement.

- Comparison of results of measurements in the series (the comparison charts on the display of the hardness tester).
