Portable hardness testers
Portable hardness testers are designed for non-destructive control of articles in shop, laboratory and field conditions, for testing hardness of metals and alloys on the following hardness scales:
- main: Rockwell (HRC), Brinell (HB), Vickers (HV) and Shore (HSD);
- additional: scale "б" Rockwell (HRB), Superficial Rockwell scale (HRN and HRT), Leeb (HL) and other.
They make it possible to test hardness of metals significantly different in their characteristics from steel (aluminum, copper alloys etc.) and determine tensile strength of articles made of carbon steel of pearlitic category.
Exceptional accuracy of measurements is provided by the transfer of hardness values from the State Hardness Standards of RF directly to portable hardness testers, omitting intermediary links of the state verification chain.
Direct testing on the main hardness scales (Rockwell, Brinell, Vickers and Shore) is reached due to the calibration using only hardness reference test blocks without any conversion tables which are "wired-in" the software of other hardness testers thus increasing their measurement error.
The possibility to calibrate hardness tester independently (in several minutes) which allows to restore precision of hardness tester readings in case of possible depreciation of the tester mechanical parts (spring, hammer) in the process of intense operation.
Convenience of data transfer and processing on the computer is reached due to hardness tester connection to USB-port and the use of exclusive in-house software which allows to reduce the data processing time considerably.
High degree of protection of aluminum, hermetically sealed, dust- and waterproof thermo resistant body of the electronic module..
2 year of guarantee maintenance and further technical support.
Advantages in comparison with stationary hardness testers
Operation with the surface layer of metal: stationary hardness testers force through the surface layer under big loads, which was subject to melting, metallizing, thermal and other surface treatment of metals.
Large-sized articles and hard-to-reach places: for stationary hardness testers this type of control is impossible due to technical and design constraints.
Measurement on site: portable hardness testers make it possible to test hardness of article on site, where it is manufactured and utilized, in shop, laboratory and field conditions.
8 hardness scales: rapid hardness test of an article on 8 different hardness scales (as compared with 1-3 scales for stationary hardness testers).
High productivity: the time of one test by portable hardness tester is 5-10 times less than the time needed to conduct testing by stationary hardness tester.
The use for testing articles with coarse grain structure (for example, cast iron) or mass more than 0,01 kg, or thickness less than 1 mm is limited. For a detailed consultation, please, contact our specialists.
