The uBRV-187.5/250 is a digital universal hardness tester manufactured by Mikrosize, a company known for the quality and reliability of its hardness testing instruments. This guide explains, in eight minutes of reading, how to set up the tester, run a test and read the results.
Installation
When you unpack the instrument, check that all components are present: the main unit, the power cord and the accessories. Connect the tester to the mains and switch it on. The display lights up and shows the start-up screen.
Test procedure
The uBRV-187.5.250 offers a wide range of functions and can test materials from metals to plastics. First, select the hardness scale to be used; common options are Rockwell, Brinell and Vickers. Use the buttons on the front panel to choose the scale from the menu.
Once the test type is selected, prepare the sample. Its surface must be clean and flat. Place the sample firmly on the sample stage. The stage is easy to adjust: raise or lower it to set the correct distance between the indenter and the sample.
Setting the test parameters
Two parameters must be set: the test load and the dwell time. The load determines the force with which the indenter penetrates the sample, and the dwell time is the period for which that load is held. Set both according to the material being tested and the testing standard being applied.
Running a test
Press the start button. The indenter lowers onto the sample, applies the load, holds it for the set time and then retracts. The result appears on the screen shortly afterwards. The tester provides a high level of accuracy across the full measuring range.
Reading the results
Once the test is complete, the results can be analysed. The tester reports not only the hardness value but also data such as the indentation depth. Results can be saved for later reference, and the tester can be connected to a PC to transfer the data.
Summary
The uBRV-187.5.250 Digital Universal Hardness Tester is simple to operate, accurate and versatile. Whether you work in a research laboratory or on a production floor, it covers routine hardness testing needs. Start testing with your uBRV-187.5.250 today.
