Dead Weight Tester

Dead weight tester is a highly efficient calibrating tool which is used to calibrate all types of measurement instruments. Suitable for testing both analogue and digital type of devices for measuring time, pressure, temperature and another type of parameters. The user just needs to connect the device to the calibrator using the union connector. The working principle of the device is pressure balance. Used widely in research labs, industries, quality control department etc. It uses NABL certified known weights for exerting pressure on a fluid until it reaches to the equilibrium condition. Post reaching equilibrium, the user can check if the reading shown in the device under test is accurate or not. The machine doesn’t require any electrical input, works using simple mechanisms without any operative complications. It strictly adheres to international test standards.
