P3000 Pneumatic Deadweight Testers


The P3000 Series is a 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 instruments is supplied with a detachable lid that 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 ISO 17025 accredited calibration certificate, operating fluid (where applicable), spare seals, adaptors for 1/8, 1/4, 3/8, 1/2″ NPT and BSP, and metric adaptors (M20 and M14).

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).
