Precision Pressure Gauge Calibrator

Product Code: 1.06.01/ATICO55453

Precision Pressure Gauge Calibrator Manufacturer


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 capstan-operated 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 calibrated.

A spirit level and adjustable feet are provided to enable the operator to level the instrument. A flotation indicator mounted on the top plate removes the guesswork when floating the piston.

The instrument is supplied complete with necessary weights and a fitted carrying case. ⅛”, ¼”, ⅜”, ½” BSP and NPT female adaptors are included together with spare seals and a quantity of oil.
