Deadweight testers are the basic primary standard used worldwide for the accurate
calibration of pressure gauges, pressure transducers etc. The equipment is self-contained and
portable, so it may be used in lecture theatre demonstrations or as a master calibrator for
the laboratory. The instrument combines a low and high-pressure range provided by two
pistons of different effective area. Calibration is accurate to within ±0.025% of reading. A
laboratory calibration certificate is supplied for each piston together with a traceable
certificate of overall accuracy. The pressure in the system is produced by means of a capstanoperated hydraulic ram, balanced by a deadweight acting upon a piston of known area. Oil is
used as the hydraulic fluid. The pressure developed is applied to the gauge that is to be
