P3100 Hydraulic Deadweight Testers


The P3100 Models are available in single or dual piston formats for increased operating ranges.  Units can be supplied in psi, bar, kg/cm2 and MPa.  These robust instruments are highly accurate, and easy to use.  Units feature a built-in priming pump for large volume applications, piston flotation indicators and 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 an accredited calibration report, weight mass details, M14 x 1.5, M20 x 1.5, 1/8″, 1/4″, 3/8″ and 1/2″ NPT and 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).
