・This is the small and lightweight deadweight tester designed with piston pressurization.
・Two pressure connections are available for conducting simultaneous two tests. (Single test available by　operating valve)
・Clear tank enables to see tank remaining level and the dirt of water.
・Piston and cylinder are precisely fabricated. Operating media is water with less viscosity so that stable and high 　sensitive measurement are possible.
・Less piston area and weight as compared to conventional deadweight tester. (1/2 of oil type)
・There is no need to prepare for “Tank siphon” even when use no oil pressure gauge should be tested.
・Standard pressure tester can be utilized for measurement.
・The pressure gauge can be easily mounted and dismounted from the mounting base with the quick fastening　nut.
・NKS Inspection Certificate and Pressure standard Inspection available.
