HBRVU-250 Optical Blowe All round Hardness Tester
HBRVU-250 Optical Blowe All round Hardness Tester
Product details
Product Introduction
HBRVU-250Blowe optical hardness testerThere are 7 levels of testing force and three testing methods available for users to choose from. Among them, Vickers hardness (HV) of 30 and 100 have a secondary test force; Brinell hardness (HB) of 31.25, 62.5, and 250 have three levels of test force; Rockwell hardness (HRA, HRB, HRC) of 60, 100, and 150 has three levels of testing force, which can meet the needs of users for various hardness tests
Functional Features
●The Rockwell hardness value is directly read by an optical projection screen
●Vickers and Brinell hardness values are measured by a microscope device (measured in two perpendicular directions), and their arithmetic mean is obtained by looking up a table
●The loading, holding, and unloading of the test force are controlled by semi-automatic control, and the speed is controlled by the flow rate of the buffer
●This instrument has high sensitivity and stability, strong operability, and is widely applicable to workshops and laboratories
