Lever type dead weight force calibration machine

Description Applications Contact us

The 50kN lever type force standard machine is taking dead weight mass as the standard load, and automatically and smoothly applies the load to the load cell to be calibrated.

It is used for testing and calibration of tension and compression load cell, also can be used for testing and calibration of proof ring. This machine includes main frame, control cabinet, computer and software, etc.
