Deadweight Tester LDW 1000

Product Description

Deadweight Tester (Pressure Balances) are the most accurate instruments for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of pressure, according to its definition as a quotient of force and area, and the use of high-quality materials result in small uncertainties of measurement and an excellent long-term stability of five years. For these reasons, deadweight testers have already been used in calibration laboratories of industry, national institutes and research labs for many years.

Due to the integrated pressure generation and the purely mechanical measurement principle, Deadweight Testers LDW 1000 are ideally suited for on-site use as well as service and maintenance purposes.

The core of Deadweight Tester LDW 1000 is a piston-/cylinder system of tungsten carbide. Besides this high-quality material, which primarily stands out for its small temperature coefficient, the workmanship of the system is a measure of the final accuracy of the pressure balance. Several refinement processes ensure a highquality and even surface with small grabs of only a few micrometer.
