Precision Pressure Gauge Calibrator (MODEL ME-FM-1260E-R)

ARL’s 1260E Dead-weight 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 theater demonstrations or as a master calibrator for the laboratory.

 
 
  • Portable, self-contained deadweight precision pressure gauge calibrator
  • Calibration gauges with 1-1,200 bar range to ±0.025% of reading
  • Supplied complete with laboratory calibration certificate
  • Includes carrying case and weights
  • Minimum standard weight increment is 0.05 bar
  • The direct measurement of pressure (p=F/A)
  • Masses added are proportional to the target pressure

  • Dual pistons enable calibration over a wide range of pressures

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 adapters are included together with spare seals and a quantity of oil.
