详细说明
This hardometer wins National Quality Second Prize in 1989. It is used to determine Rockwell hardness of ferrous metal, nonferrous metal, nonmetal material and product. It is widely applied to lab of factories, mines, scientific research unit and college.Spindle system adopts non-friction spindle structure; electromagnetic brake controls initial test force so as to improve precision of initial test force. Automated application, maintain and removal of total test force eliminate error caused by manual operation. Automatic digital display of value of hardness completely avoids reading error of operator. Random printer can print value of hardness and data processing result.
