Hydraulic Deadweight Testers
A selection of deadweight testers with varying ranges and measurement units, these instruments are able to calibrate pressure sensing instruments via the creation of hydraulic pressure. More sophisticated models can be used to calibrate pressure calibrators.

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.
