Advantages
Implements the ultrasonic contact impedance (UCI) method and the rebound (Leib) method.
- a combination of both methods allows to control all metal products;
- 2 replaceable probes: ultrasonic U1 and dynamic D1;
- no restrictions in hardness control (by weight, configuration, structure, degree of mechanical and thermal treatment, etc.);
- allows you to estimate the change in hardness of the hardened layer by the depth of the product and the effect of surface stresses;
- implements the principle of ultrasonic contact impedance when working with an ultrasonic probe and the rebound principle when working with a dynamic probe;
- two hardness testers in one - convenient, profitable: MET-UD price = [price (MET-U1) + price (MET-D1)] - 25%.
The UCI method is most suitable for hardness control of homogeneous materials and for thin or light by weight of the products, where other portable testing methods are unreliable or inapplicable.
The rebound method is very simple, productive and does not require special skills. It is especially suitable for hardness measurements on massive products, products with a coarse-grained structure, forged and cast products.

Calibration, verification, certification
The initial verification of hardness testers is carried out when the hardness testers are released from production. A "Verification Certificate" of the established form is issued for the hardness testers, which is included in the hardness tester delivery set.
Verification and calibration of portable hardness testers of the "MET" series is carried out according to the main hardness scales HRC, HB, HV, HSD.
Calibration according to additional (user) scales H1, H2, H3 (for example, according to the hardness scales HBW, HRB, HRN, HRT, etc.), as well as for metals that differ significantly in properties from steel (for example, aluminum and copper alloys, etc.) is carried out by the user according to the instructions provided in the hardness tester passport. The Rm scale of tensile strength is available, which is calculated from the HB scale according to GOST 22761.
The frequency of verification of hardness testers is once a year. Verification can be carried out by any metrological service of legal entities accredited for the right to verify hardness measuring instruments, regional Centers for Standardization and Metrology (CSM). The verification method together with the Passport are included in the hardness tester kit.
