Digital Brinell Hardness Tester TDBH-A10 with advanced design tests the hardness of the material on Brinell scale. The traditional method of using heavy weights for Brinell testing is replaced by using photo/pressure sensor with more accurate results. It is used to determine the Brinell hardness of cast-iron, ferrous & non-ferrous metal, soft alloys & other nonmetallic materials. The digital display controls parameters like dwell time, test force etc.
