Portable Combined Hardness Tester MET-UD
MET-UD portable hardness tester was for the first time presented at the International exhibition "Industrial Non-Destructive Control" in 2002. A year later, German company "Krautkramer" started the production of MIC 20 combined hardness tester. At present, these are the only hardness testers of this type in the world.
Main possibilities
Aluminium body
Plastic body
- measurements of hardness of metals and alloys on standardized in Russia hardness scales: Rockwell (HRC), Brinell (HB), Vickers (HV) and Shore (HSD).
- three additional scales H1,H2, H3 for calibration (upon request) of other hardness scales (Rockwell "B", Superficial Rockwell, Leeb etc.), and also hardness scales for metals different in their characteristics from steel (for example non-ferrous metals, alloys, cast iron etc.);
- use of tensile strength Rm scale in accordance with GOST 22791-77 for determination of tensile strength of articles made of carbon steel of pearlitic category by means of automatic recalculation from Brinell hardness scale (HB);
- connecting upon request shortened probes U1/2 and D1/2.
Distinctive features
Implementation of rebound and ultrasonic contact impedance method (UCI).
- combination of both methods allows to test all article made of metals;
- two changeable probes: U! ultrasonic and D1 dynamic;
- no limitations in the process of hardness testing (by weight, configuration, structure and degree of mechanical and thermal treatment etc);
- allows to estimate the change hardened layer hardness along the depth and influence on surface tension;
- two hardness testers in one - this is convenient and profitable: the price of MET-UD = (METU1+METD1) - 20%.
Principle of operation
Determination of indenter free oscillation frequency (acoustic resonator with Vickers diamond pyramid) under the constant force of 1,5 kgf.
Determination of ratio of indenter speed before and after the impact on the surface of the tested article.
Guarantee and technical maintenance
- 1 year of guarantee maintenance and the further technical support.
Operation demonstration
It is possible that our specialist can demonstrate the operation at your premises within Moscow.
