About Hydraulic Deadweight Testers

A deadweight tester is a calibration standard that uses the principle of a pressure balance to calibrate pressure-measuring instruments. Deadweight testers use calibrated weights to apply known pressures to a device under test for a simple and cost-effective solution that covers a wide range of pressure calibrations.

Oil deadweight testers are a time-tested solution for pressure calibration, providing reliable, repeatable results. However, water deadweight testers are the preferred solution when calibrating devices that cannot be exposed to oil contamination. Electronic versions (E-DWT) are electronic replacements for traditional deadweight testers.
