Hydraulic Comparison Test Pumps The Pressurements Series of hydraulic test pumps are used for checking pressure measuring instruments against master test gauges, indicators or transducers. These cost effective instruments, which include several features from our popular line of hydraulic deadweight testers, are capable of easily generating high pressures and provide precise control for important calibration requirements.
Pneumatic Comparison Test Pumps These pneumatic comparison test pumps are designed for testing pressure measuring instruments against master test instruments. These cost effective instruments provide precise control for important calibration requirements and include many features found in our popular line of pneumatic deadweight testers.
Media Separators Liquid/Liquid and Liquid/Gas media separators are provided as a barrier between the deadweight tester operating fluid and that of the device under test.
Dirt/Moisture Traps Dirt/Moisture Traps provide an effective barrier against the transfer of moisture and dirt from an instrument under test to the sensitive piston/cylinder assembly of a pneumatic deadweight tester. Unexpected particle contamination or fluid inside the device under test will be prevented from entering the deadweight system, avoiding downtime for maintenance or repair. Designed for operation in the vertical position these traps are simple to dismantle and easy to clean.
