Fluke P3123-BAR Deadweight Tester

Overview

The Fluke P3123-BAR is a dual piston-cylinder unit (PCU) deadweight tester providing exceptional pressure calibration capability from 1 to 350 bar. The dual piston design enables extended operating range without requiring multiple instruments. With certified accuracies traceable to NIST and proven piston-gauge technology, it serves as a primary pressure standard for versatile calibration applications in laboratories and industrial environments.
