Fluke P3031-BAR Gas Deadweight Tester, Liquid Lubricated, 70 BAR
The Models P3031 and P3032 feature a gas driven oil lubricated piston/cylinder assembly which ensures that the instrument is less susceptible to performance issues due to contamination or the operating environment. These gas driven deadweight testers eliminate the maintenance issues associated with conventional high pressure pneumatic deadweight testers. The supply gas acts directly on the oil lubricated pistons so there is no effect on system accuracy.
