Features
• The most comprehensive range
• Gauge pressure
• Absolute pressure
• Vacuum
• Separators and comparison test pumps
Deadweight testers are the basic primary standard used
world-wide for the accurate measurement of pressure.
No other piece of equipment can match the stability,
repeatability and accuracy of the deadweight tester. It is
ideal for calibrating pressure gauges, transducers,
transfer standards, recorders, digital calibrators, etc. and
can also be used to directly measure the pressure in
systems and processes where precise readings are
important.

GE
Sensing
Using the well proven piston gauge system, which
consists of a vertically mounted precision lapped piston
and cylinder assembly, accurately calibrated masses are
loaded onto the piston, which rises freely within its
cylinder. These weights balance the upward force
created by the application of pressure within the system.
GE offers one of the most comprehensive series of
deadweight testers available, covering a wide variety of
applications and ranges of pressure and vacuum. The
piston assemblies are manufactured to the very highest
standards with certified accuracies traceable to
international standards laboratories such as the National
Institute of Standards and Technology (NIST).
Gravity varies significantly with geographical location
and this variation has a direct effect on the force of the
weights and the accuracy of the deadweight tester. Each
instrument can be calibrated to local gravity at no extra
cost. If unspecified, instruments will be supplied
calibrated to standard gravity 980.665 cm/s2.
Instruments are supplied with an integral carrying case,
making them neat, compact and easily portable.
Components are stored in the detachable lid, which also
provides excellent protection from dirt and damage
when the tester is in transit or storage. Unique test
station connections allow quick hand-tight sealing, no
need for polytetrafluoroethylene (PTFE) tape and
wrenches. A spirit level and adjustable feet are provided
to enable the operator to level the instrument. A flotation
indicator is mounted on the top plate, removing
guesswork when floating the piston. Weights are stored
in a separate box.

• 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.
