Dwyer Instruments 2000-00 Magnehelic Differential Pressure Gauge 0-0.25 Inch WC

The Dwyer Instruments 2000-00 Magnehelic Differential Pressure Gauge provides accurate, reliable measurement of low differential pressures in HVAC systems, clean rooms, filter monitoring, and industrial applications. This precision instrument measures pressure ranges from 0 to 0.25 inches of water column (WC) with exceptional accuracy.

Key Features:

• Pressure range: 0-0.25 inches water column
• Magnehelic movement provides long-lasting accuracy without mercury or bellows
• 4-inch dial with easy-to-read graduated scale
• Dual pressure ports accept tubing connections up to 3/16 inch ID
• Accuracy: ±2% of full scale
• Compact design with built-in mounting holes for panel or surface mounting
• No external power required for operation
• Durable aluminum case construction

The Magnehelic gauge utilizes a proven diaphragm-actuated magnetic movement that eliminates the need for pivots, gears, or linkages. This design ensures minimal friction and drift for long-term reliability. Ideal for monitoring air filter pressure drops, damper position verification, fan performance testing, and general low-pressure measurements in commercial and industrial environments.
