Combined hardness tester MET-UDA

Combined hardness tester MET-UDA

Hardness tester MET-UDA operates according to ultrasonic contact impedance method (UCI) at the connection of an ultrasonic probe according to the standards ASTM A 1038, DIN 50159, and rebound (Leeb) method at the connection of a dynamic probe according to the standards ASTM A 956, DIN 50156.

Combination of both methods enables to perform hardness control of all metal articles;

2 changeable probes: ultrasonic and dynamic;

No limitations during hardness control (on mass, configuration, structure and degree of mechanical and thermal treatment, etc.);

Allows to estimate the change in hardness of a hardened layer along the depth of the article and the influence of surface tension;

Operates according to ultrasonic contact impedance method at the connection of an ultrasonic probe and according to rebound effect at the connection of a dynamic probe;

Two hardness testers in one - it is convenient and profitable:

cost of МЕТ-UD = [cost of (МЕТ-U1) + cost of (МЕТ-D1)] - 25%.

UCI-method enables to control the hardness of metal and alloy items of any weight and dimensions, but is mostly suitable for measurements on the surface of thin and light articles with homogeneous structure that cannot be measured using the dynamic rebound method (Leeb).

The rebound (Leeb) method is very simple, productive and does not require any special experience. It is particularly suitable for hardness measurements on massive articles, materials with coarse-grained structure, forged and cast articles.
