The P3000 Hydraulic Deadweight Tester.
Pressure ranges:
Oil operated: Ranges to 20,000 psi (1400 bar)
Distilled water operated: Ranges to 10,000 psi (700 bar)
The P3000 Series Deadweight tester is the culmination of over 50 years experience in the production
and design of primary 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.
