Advantages
The device is the smallest on the market of portable hardness testers in the Russian Federation.
It implements the ultrasonic contact impedance (UCI) method. The UCI method is most suitable for testing the hardness of homogeneous materials and for thin or light-weight products, where other portable testing methods are unreliable or inapplicable.
-
the MET-MINI hardness tester reliably measures the hardness (according to Rockwell, Super Rockwell, Brinell, Vickers and other scales) of metal products with a thickness of more than 1 mm;
-
an ultrasonic sensor and an electronic unit in one high-strength aluminum housing;
-
the screen is protected by tempered glass
-
the smallest size of ultrasonic device in the world;
-
the ability to calibrate the hardness tester by two hardness measures;
-
connection to the computer via USB port - statistical processing, upload to MS EXCEL;
-
fits easily in your pocket and weighs only 300 grams;
-
the hardness tester is included in the state register of measuring instruments of the Russian Federation under No. 86618-22;
-
warranty - 3 years;
- The basic set includes a standard hardness measure.
Package
- Hardness tester MET-MINI
- USB cable
- Power supply for charging
- MTR-MET Rockwell hardness tester 25±5 HRC 2 categories
- Certificate of verification of hardness tester and hardness tester
- Passport
Calibration, verification, certification
Primary 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. A record is made in the FGIS "ARSHIN".
Verification is carried out according to hardness scales
-
HRC, HB, HV – by default.
-
HBW, HV, HR(T,N)(15,30,45) - on request.
Calibration on additional (user) scales 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, or upon request by company specialists.
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.
