Pressure reference-dead weight tester

Dead weight testers are the most accurate instruments avaliable on the market for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of the pressure (p=F/A), as well as the use of high-quality materials enable a very small uncertainty, in conjunction with wxcellent long-term stability. The dead weight tester has therefore been used for years in factory and calibration laboratories in industry,national institutes and research laboratories.

Our DWT (CW series) adopt unbreakable piston rod and high accuracy(up to 0.005%), which make it much longer lifetime and accurate result as pressure reference instrument.
