Dead Weight Tester (Grade II standard)

Performance Characteristics: 1. Both piston and the piston cylinder undergoes the careful attrition to make ,they are adopt high strength, high hardness, and the low-temperature coefficient of linear expansion hard alloy tungsten carbide material,, the working conditions temperature is wide, stable property 20±5°C. 2. The load center of gravity is low, the weights through hang basket directly add on the piston, the piston revolution is steady, the fluctuation of pressure is minimum, shows the value to be accurate. 3. Above 25MPa (250kg/cm2 ), pressure transmission medium uses the Diisooctyl Sebacate which viscosity very small , thus ensuring that the manometer has extremely high sensitiveness thereby. 4. Weights all adopt non-magnetic stainless steel making which the pressure gauge used. 5. The piston working position with the position transmitter monitor, the piston high and low traveling route for ±1.5mm, the measuring appliance demonstrated that has sensitive, striking, accurate and so on merits.
