Dwyer Instruments 2000-00N Magnehelic Differential Pressure Gauge 0-0.20 Inch W.C.

The Dwyer Instruments 2000-00N Magnehelic Differential Pressure Gauge is a precision instrument designed for measuring extremely low differential pressures in HVAC, clean room, and industrial applications. This gauge features a 0.05-0-0.20 inches water column (w.c.) range, making it ideal for monitoring filter conditions, air velocity, furnace draft, and pressures in ducts and fans.

Key Features:

• Measurement range: 0.05-0-0.20 inches water column with bidirectional scale
• Large 4-inch dial face for easy reading from a distance
• Patented Magnehelic movement requires no oil or transmitting fluids
• ±2% full scale accuracy for reliable measurements
• Simple two-screw panel mounting with built-in mounting holes
• Dual pressure ports accept 1/8" ID tubing or 10-32 threaded fittings
• Durable polycarbonate case suitable for industrial environments
• Zero adjustment screw for field calibration

The Magnehelic gauge uses a frictionless Magnehelic movement that eliminates drift and hysteresis common in mechanical gauges. Its sensitive diaphragm responds instantly to pressure changes, making it perfect for monitoring critical HVAC systems, clean room pressurization, and filter status. The gauge can be panel-mounted or used as a portable instrument with optional accessories.
