YS Tungsten Carbide Dead Weight Tester For Laboratory
Presusre Gauge Calibrator Dead Weigtht Tester Piston Gauge
Description Presusre Gauge Calibrator Dead Weigtht Tester
Deadweight tester (DWT) is a calibration standard which uses a piston cylinder on which a load is placed to make an equilibrium with an
applied pressure underneath the piston.Deadweight testers are so called primary standards which means that the pressure measured by a deadweight tester is defined through other quantities; Length, mass and time.Typically deadweight testers are used in calibration laboratories to calibrate pressure transfer standards like electronic pressure measuring devices.
