Fluke P3031-PSI Gas Deadweight Tester

Overview

The Fluke P3031-PSI is a liquid-lubricated gas-operated deadweight tester designed as the primary standard for pressure measurement and calibration. The piston/cylinder assembly is lubricated with mineral oil, providing excellent resistance to contamination from gas supply or environmental sources. This model covers pressure ranges from 10 to 1,000 psi with exceptional stability and repeatability.
