Dwyer Instruments 2003 Magnehelic Differential Pressure Gauge 0-3 Inch WC

The Dwyer Instruments 2003 Magnehelic Differential Pressure Gauge is a precision instrument designed to measure low differential pressures in air and non-combustible, non-corrosive gases. This model features a 0-3 inches of water column (w.c.) pressure range, making it ideal for applications requiring highly sensitive pressure measurements.

Key Features:

• Measurement range: 0-3 inches water column differential pressure
• Magnehelic technology provides accurate, reliable readings without requiring external power
• Large 4-inch dial face for easy reading from a distance
• Durable die-cast aluminum case construction
• Two 1/8" NPT female pressure connections on back of housing
• Accuracy: ±2% of full scale at room temperature
• Can be surface or flush mounted with optional accessories
• Zero adjustment screw for field calibration

The Magnehelic gauge is widely used in HVAC systems for measuring filter pressure drops, duct pressures, and static pressures. It's also popular in industrial applications including clean room monitoring, laboratory fume hood control, and process monitoring. The self-contained design requires no external power source, making installation simple and reliable.
