Dwyer Instruments 2001AV Magnehelic Differential Pressure Gauge 0-1" WC

The Dwyer Instruments 2001AV Magnehelic Differential Pressure Gauge is a precision instrument designed for measuring low differential pressures in HVAC, cleanroom, and industrial applications. This reliable gauge features a 0-1 inch water column (WC) pressure range with a secondary scale showing 0-4000 feet per minute (fpm) air velocity.

Key Features:

• Dual scale display: 0-1" WC pressure and 0-4000 fpm air velocity
• Magnehelic movement provides accurate, drift-free performance without liquids or linkages
• 4-inch dial for easy reading from a distance
• ±2% full-scale accuracy for reliable measurements
• Durable aluminum case construction with clear acrylic lens
• Low differential pressure range ideal for filter monitoring, air flow measurement, and HVAC system balancing
• 1/8" NPT female pressure connections for easy installation
• Can be panel or surface mounted with included hardware

The Magnehelic Series 2000 gauges are industry-standard instruments trusted by HVAC professionals, facility managers, and engineers for their proven reliability and long service life. The frictionless Magnehelic movement eliminates the need for recalibration over extended periods, reducing maintenance costs and downtime.
