Dead Weight Pressure Gauge Tester
Description
The Dead Weight Pressure Gauge Tester is precision built primary pressure standards, used for testing, setting, calibrating or repairing pressure measuring devices within the test points 15 psi (100kPa) to 10,000 psi (70,000kPa).
Pressure calibration points produced by the deadweight tester are accurate to within ± 0.1% of the reading certified traceable to the N.I.S.T. The tester provides consistent, repeatable accuracy, maintaining its pressure for an appreciable length of time regardless of temperature changes, slight leaks in the pressure system, or changes in volume of the pressurized system due to movement of a Bourdon tube or other device.
