Product Description

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.


Purpose:
      In 1980,Model : YS-6; YS-60; YS-600 Dead Weight Tester Pressure Tester  were awarded the state silver medal. And in 1987, after re-examination , we still hold the state silver medal.
      These testers are used in laboratory and measuring department for calibrating the precision pressure gauges or standard pressure gauges.
