Deadweight Tester

Nagman lnstrument & EIecctronics, in association with Pressure- ments Ltd, U.K., offers a comprehensive series of deadweight testers. These cover a wide range of pressure and vacuum for a variety of applications. The identical piston assemblies of these testers are of very high standard, with certified accuracies traceable to National Physical Laboratory, U.K., and NIST, U.S.A. Basically, deadweight testers are the primary standard used world-wide for accurate measurement of pressure. No other piece of equipment can match the stability, repeatability and accuracy of the deadweight tester. It is ideal for calibrating pressure gauges, transducers, transfer standards, recorders, digital calibrators, etc, and can also be used to measure directly the pressure in systems and processes where precise readings are important. Well proven piston gauge system, consisting of a vertically mounted precision lapped piston and cylinder assembly, is used. Accurately calibrated masses are loaded onto the piston, which rises freely within its cylinder. These weights balance the upward force created by the application of pressure within the system. The testers are available in different models and ranges from 0.03 bar to 4000 bar and different accuracies down to 0.005 % of reading.
