Dwyer Instruments 2002 Magnehelic Differential Pressure Gauge 0-2 Inches Water Column

The Dwyer Instruments 2002 Magnehelic is a highly accurate differential pressure gauge designed for measuring low air pressure in HVAC systems, cleanrooms, filter monitoring, and industrial applications. This analog gauge features a 0-2 inches water column (w.c.) pressure range, making it ideal for monitoring air filters, ventilation systems, and duct pressures.

Key Features:

• Pressure range: 0-2 inches water column (w.c.)
• Accurate to ±2% of full scale
• Magnehelic diaphragm technology for reliable, long-term performance
• Large 4-inch dial for easy reading from a distance
• Die-cast aluminum case construction for durability
• Available in panel or surface mounting configurations
• Dual pressure ports for differential pressure measurement
• No external power required for operation

The Magnehelic gauge uses a proven design with a frictionless magnet and helix system that ensures accurate readings without mechanical wear. The color-coded dial face allows for quick visual reference, and the zero adjustment screw enables easy field calibration. This gauge is widely used across commercial HVAC, pharmaceutical cleanrooms, hospital ventilation systems, and industrial process monitoring applications.
