\nSummary:
\nBrinell hardness testing is the largest indentation hardness test of all the testing method; it can reflect the overall performance of the materials, but cant be influenced by the sample organization and composition micro-segregation uneven, so it is a hardness test of high precision. It is widely used in metallurgy, forging, casting, without hardened steel and non-ferrous metals industries, laboratories, universities and scientific research units. It is the closed loop sensor loading, the electronic automatic loading system, has 10 levels test force. The machine has high precision, high repeatability and stability, easy operation.
\nApplication Areas:
\nSuitable for the precision testing of parallel plane,
\nStable and reliable for the curved surface testing .
\nApplication Materials:
\nFerrous metals, nonferrous metals and bearing alloy material
\nFeatures:
\nLarge digital LCD high resolution displaying screen, menu smart tips and flexible and convenient operation functions;
\nAutomatically input indentation diameter, directly display the hardness value, any hardness can be shown in two modes of unit, without checking the reference table;
\nFull automatic close-loop transducer control system;
\nBuilt-in printer, equips with RS-232 data port, suitable to connect to PC;
\nEquips with digital microscope and precise data calculating system, can immediately display result after a gently press;
\nStrong structure, good rigidity, high testing accuracy and efficiency, durable and reliable performance;
\nEmploys electron loading instead of weight loading, auto-protection against overload and over-bit;
\nFull automation testing course, without man-made error;
\nMachine shell is made of a casting, with structural stability, which will not deformed, can work under more harsh environment;
\nSuitable to install with optional CCD brinell indentation image processing system device (see picture below);
\nThe machine accuracy is in line with GB\/T231.2, ISO 6506-2 and American Standard ASTM E10.
