This equipment is used to determine the Brinell hardness of steel bottle after heat treatment. It can remove the oxidation-layer on the surface of work piece, finish Brinell hardness test, catch indentation by a CCD system and display the Brinell hardness number automatically. The specially designed software can be used for storage, statistic, edit, analysis of the testing data.
★ Automatically remove the oxidation-layer on the surface of work piece
★ The surface removing depth is adjustable
★ The upper computer PC controls the lower computer PLC / single chip
★ Test force closed loop control
★ The measuring head can finish the hardness test automatically
★ The CCD measuring system can finish the Brinell indentation measurement automatically and then display the hardness number
★ Double display screens, powerful software function (data processing, hardness conversion etc.)
★ Precision conforms to GB/T 231.2, ISO 6506-2 and ASTM E10
