Fluke P3112-PSI Single Piston Oil Deadweight Tester
Includes: Fluke P3112-PSI accredited calibration report, weight mass details, M14 x 1.5, M20 X 1.5, 1/8 inch, 1/4 inch, 3/8 inch and 1/2 inch NPT and BSP female adaptors, operating fluid (where applicable) and spare seals.
Fluke P3112-PSI Hydraulic Deadweight Tester - Oil Operated - Single PCU - Pressure Range 40 to 2000 psi.
These robust instruments are highly accurate, quick and easy to use. Units feature a built-in priming pump for large volume applications, piston flotation indicators and a high quality screw press for fine pressure control.
The Fluke P3100 Series is the culmination of over 50 years of experience in the production and design of high performance pressure standards. With features designed to improve accuracy and performance, increase reliability and simplify operation these deadweight testers can be used to calibrate virtually any pressure sensing device, including transducers, transmitters, gauges or pressure switches.
Each instrument is supplied with a detachable lid which makes it neat, compact and easily portable. The weight masses are stored in a high-quality case with a self locking mechanism to protect them during transit.
NB: 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 calibrated to Standard Gravity at 980.665 cm/s2.
