Digital Multifunctional Brinell Rockwell Vickers Hardness Tester
iqualitrol 420HBRVS-187.5 with Touch Screen
Main Feature:
● iqualitrol 420HBRVS-187.5 is a multi-functional hardness tester
with motorized force loading which can test Brinell, Rockwell and
Vickers hardness scales;
● Use ARM high-speed processor, 8-inch LCD touch screen, convenient
interface operation;
● Touch screen can display current test scales, test force, loading
time, hardness conversion value, indenter type, etc.;
● Automatically control the force loading, dwell, and unloading;
● The uniquely designed electromagnetic braking function, the
initial testing force is applied in place, the screw and hand wheel
are automatically locked, and then the main test force is
automatically applied to eliminate human errors and improve the
measurement accuracy;
● Automatic compensation for testing force, high accuracy of
strength; the hardness value of the convex surface can be
automatically corrected;
● With software calibration function; dynamically display
displacement-force value curve dynamically, which is easy to
observe and analyze;
● The upper and lower limits of the test hardness can be set, and
the hardness over-limited automatically prompts;
● Support various hardness scales conversion;
● With USB and RS232 data interfaces to facilitate users to process
data;
● With database storage data function, test data synchronous
storage and export;
● With built-in printer, you can directly print the hardness test
results;
● Optional upper -bit machine system to perform data upload and
intelligent control operation;
● accuracy conforms to GB/T230.2, GB/T231.2, GB/T4340.2; ISO6508-2,
ISO6506-2, ISO6507-2, and the United States ASTM E18, ASTME10, ASTM
E92.
