Dwyer Instruments 2015 Magnehelic Differential Pressure Gauge 0-15" WC

The Dwyer Instruments 2015 Magnehelic Differential Pressure Gauge is a reliable, industry-standard instrument designed for measuring positive, negative, or differential pressures in air and non-corrosive gases. This gauge features a 0-15 inches water column (w.c.) pressure range, making it ideal for monitoring filter conditions, airflow, pressure drops, and HVAC system performance.

Key Features:

• Accurate ±2% full-scale measurement with easy-to-read 4-inch dial
• Magnehelic movement eliminates need for liquids, pistons, or bellows
• Durable plastic case construction with shatterproof polycarbonate lens
• Dual 1/8" NPT bottom connections with integral flush-mount back panel
• Zero adjustment screw for field calibration
• No external power required for operation
• Range: 0-15 inches water column

The Magnehelic gauge's frictionless magnet-and-helix design provides years of reliable service with minimal maintenance. Widely used in cleanrooms, hospitals, laboratories, industrial facilities, and HVAC applications for monitoring filter loading, duct pressures, and air velocity stations.
