Fluke P3111-PSI Oil Deadweight Tester Single PCU
Deadweight Tester
- Pressure Range 10 to 500 psi
- Accuracy better than 0.015 % of reading
- Acrylic reservoir provides visibility of fluid level and quality
The P3100 Models are available in single or dual piston formats for increased operating ranges. Units can be supplied in psi, bar, kgf/cm², and MPa. 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 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.
All units are provided with a traceable certificate of accuracy, weight mass details, 1/8 inch, 1/4 inch, 3/8 inch and 1/2 inch NPT or BSP female adaptors, operating fluid (where applicable) and spare seals.
The piston/cylinder 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).

Options
- Improved Accuracy Option with Software – PressCal Software is a Windows-based software program that allows users to easily apply all necessary corrections, allowing for improved accuracy of 0.008%. PressCal is provided as standard with all 0.008 % instruments.
- Fine Increment Weights – Additional small weights that allow for finer pressure increments
- PPA9159-CAL For use with kPa, MPa, bar, or kgf/cm2 weight sets
- PPA9608-CAL For use with psi weight sets
- Conversion Weights – Allows for an instrument to be used in a pressure unit other than the pressure unit the instrument was ordered for.
