Fluke P3031-BAR Gas Deadweight Tester

Overview

The Fluke P3031-BAR is a liquid-lubricated, gas-operated deadweight tester designed for high-precision pressure calibration. As a primary standard for pressure measurement, it employs a vertically positioned piston/cylinder assembly where calibrated weight masses counterbalance the upward force generated by pressure. The liquid lubrication system makes this model less prone to performance problems from gas supply contamination, ideal for high-pressure applications.

Key Features

• Pressure range: 1 to 70 bar
• Accuracy: ±0.015% of reading (±0.008% with PressCal software)
• Liquid-lubricated design reduces contamination sensitivity
• Piston material: Tungsten carbide for durability and stability
• Cylinder material: Martensitic steel
• Operating fluid: 55-655 mineral oil
• Piston flotation indicator for easy operation
• Screw press for fine pressure control
• Mounted spirit level and adjustable feet
• High-quality needle valves for optimum control
• Test station design with O-rings eliminates need for PTFE tape or wrenches
