Automatic Brinell Hardness Tester
$24,995.00
Fully automatic Brinell hardness tester with closed-loop load cell control, 12-inch display, auto-rotating turret, automatic focus, and 5 work stations. Test range 3.18–653 HBW. Conforms to EN ISO 6506, ASTM E-10-08, GB/T231.2.
Description
Innovative closed-loop technology. The Brinell hardness tester incorporates the latest load cell technology. The test load is applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit. The result is highly accurate Brinell hardness measurements at all test loads up to 0.5%. The common load overshoot or undershoot as known from traditional dead weight, or open-loop, systems is eliminated. The absence of mechanical weights not only eliminates friction problems but also makes the Brinell Hardness Tester less sensitive to misalignments caused by vibrations.
