Ravika Instruments Mayapuri, Delhi

Dead weight testers are named so because they utilize dead weights in determination of pressures operating in a closed and compressed fluid system. They are so called because of the reason that for each value of pressure to be exerted applied in the closed hydraulic system, a predetermined fixed amount of weights are used to exert the force to counter balance the buoyancy forces. Each weight is stamped with the equivalent amount of force that will be exerted on a predetermined area of piston cylinder arrangement by using that weight. There fore the device is called Dead Weight tester.
