Portable high precision hardness tester TKM-459CE intended for quick measuring of metal items hardness in laboratorial, manufacturing and field conditions. 

The device performs non-destructive quality control of products in metallurgy, mechanical engineering, aircraft construction, shipbuilding, nuclear industry, oil and gas industry.

The hardness tester is intended to be used for hardness measurement of carbon construction steels in basic hardness scales — Brinell (HB), Rockwell (HRC), Vickers (HV).

Hardness tester functions by UCI method (Ultrasonic Contact Impedance).

TKM-459CE controls hardness of following:

- Carbonaceous and structural steels
- Items with surface-hardened layers such as cementation, nitride hardening, high frequency current hardening
- Heat-proof, corrosion-proof, non-corrosive steels
- Plated coating (chrome), overlaying
- Items of complicated configuration

Exploitation advantages

  • Stable readings independent from force and time of pressing.
  • Easy measuring in hard-to-reach areas.
  • Ultra-small control area (from 1 mm).
  • Control in slots and blind holes from 5 mm (not provided by rival devices).
  • Invisible print on mirror-surface.
  • Low sensitivity to the curvative of surface, thickness and weight of product.

Features of TKM-459CE

  1. Impact-, dust- and water- proof housing.
  2. Intuitive graphic interface.
  3. Bright color display allows working at below zero temperature and stays bright at any lighting.
  4. Signalization of exceeding of prescribed readings threshold.
  5. Unique system of statistic data processing and averaging of readings.
  6. Fast adjustment of readings and programming of additional calibrations to basic scales by 2 or less standard blocks.
  7. Flexible device memory for recording of readings and their analysis.
  8. Programming of additional scales calibrations by 2 or less standard test blocks.
  9. Fast programming of additional scales by 2 to 10 standard test blocks.

Requirements to controlled item:

  • Items heavier than 1 kg and thicker than 2 mm need no additional preparation;
  • Items lighter than 1 kg should be fixed in a vice clamp or on a support plate by fixing paste;
  • Items thinner than 2 mm should be fixed in a vice clamp or on a support plate by fi xing paste;
  • Roughness of controlled surface providing best measurement accuracy is 1.6 RA.

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).
