Hydraulic Deadweight Testers
• *Accuracy better than 0.015% of reading. 0.008%
optional
• Dual piston models allow calibration over a wide
range. Piston automatically selected without valving or
piston exchange
• Overhanging weight carrier protects carbide piston,
improves rotational spin, sensitivity and stability.
• Water models eliminate oil contamination.
• Pressure is generated by a ram screw.

Built-In Hand Pump
• Large volume systems are easily primed
• Greatly speeds up priming and pressure generation
• Enables an effortless, small bore, high pressure ram
screw to be fitted
• There is no additional valve operation involved.
• Standard on M2800, not available on M3800 Series
Motor Drive
If a continuous pressure is required, a motor drive can be
provided to rotate the weights. Rotating the weights by
hand is satisfactory for standard calibrations.
The motor is isolated from the deadweight tester by a
thermal barrier, preventing warming of the measuring
piston. The motor is suitable for 210/250, 105/125 volts
at 50/60 Hz, please specify requirements at time of
order.
