Fluke P3123-PSI Deadweight Tester

Overview

The Fluke P3123-PSI is an oil-operated dual-range deadweight tester designed for accurate pressure calibrations in imperial units. This high-performance pressure standard uses a precision-lapped piston-gauge system and is part of the P3100 series, which represents over 50 years of experience in pressure standard design. The instrument is traceable to international standards laboratories including NIST.

Key Features

• Oil-operated with dual piston-cylinder units (PCU) for expanded pressure range
• Pressure range: 10 to 5,000 psi with 10 psi increments
• Accuracy: ±0.015% of reading (±0.008% with optional PressCal software)
