เครื่องทดสอบความแข็งโลหะ Hardness Tester Brinell BO3
In this Brinell hardness tester, a fixed load is applied to a steel ball to press a test specimen. Measurement is made on hardness by means of a diameter of a dent caused thereby. This unit is a hydraulic type Brinell hardness tester adopted most widely.
