Model No. 900-359 Innovative closed-loop technology. The Brinell hardness tester incorporates the latest load cell technology. The test load is applied via a closed-loop control unit with a load cell, a DC motor and an electronic measurement and control unit. The result is highly accurate Brinell hardness measurements at all test loads up to 0.5%. The common load overshoot or undershoot as known from traditional dead weight, or open-loop, systems is eliminated. The absence of mechanical weights not only eliminates friction problems but also makes the equipment less sensitive to misalignments caused by vibrations
FEATURES:Fully automated test cycles. Press the START key once, the Brinell hardness tester will complete the entire test cycle automatically—1)sample elevation 2)major load application 3)Dwell Time 4) Unloading.
- Equipped with CCD camera and built-in touch screen PC performs the indentation measuring process automatically.
- Hardness Measurement software includes useful functions. a) Single and batch testing mode b) Tolerance setting w/alarm c) Statistic values such as Max, Min, Avg, R and S are selectable d) Convert test result to other hardness scales, such as HRC,HRB,HRA,HV,σb.
- All hardness test results and indention images are saved automatically
- Test report created in Microsoft EXCEL format, can be edited, copied or printed.
- Load Cell driven system provides precise control of hardness test force application
