Product Information

Features

● BRV-250D is a universal hardness testing instrument for the measurement of Brinell, Rockwell and Vickers scale.

● BRV-250D equips 14-testing-foce and 5-indenter, it is universal to measure most of metal material.

● BRV-250D dwell time from 2 to 60S can be setup on large-screen touch LCD interface, it is much convenient than the setup on the manual hardness tester;

● BRV-250D loading ,dwell and unloading is driven by electronic motor automatically, doesn’t need the operator to handle it, it eliminates the human operating error maximum. The force sensor controls the test force with an accuracy of 5‰;

● BRV-250D doesn’t need the operator to read and check the hardness scale table ,it will compute and display the testing result once press the key of digital measuring microscope.

● BRV-250D equipped with a built-in printer for data output, also can use RS232 cable to connect to the computer to export the measurement report.
