Fluke P3031-KGCM2 Gas Deadweight Tester

Overview

The Fluke P3031-KGCM2 is a liquid-lubricated gas-operated deadweight tester serving 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 1 to 70 kgf/cm² with exceptional stability and repeatability.
