Differential Pressure Gauge, 0-0.5 Inches of Water, 1/8 Inch Female NPT, Aluminum Construction, ±2% Accuracy, for Air and Gas Applications, 15 PSI Rating

The Differential Pressure Gauge is engineered for precision in measuring low air or non-corrosive gas pressures in a variety of industrial and HVAC systems. With a measurement range of 0-0.5 inches of water, this gauge accurately monitors positive, negative (vacuum), or differential pressures for tasks such as measuring fan and blower pressures, filter resistance, air velocity, and more. Made of durable aluminum, the gauge is designed for air and compatible gases (excluding hydrogen gas) with an accuracy of ±2% of full scale at 70°F. It features 1/8 inch female NPT connections for both high and low-pressure taps and offers dual side and back connections for versatility. This gauge is perfect for applications like furnace draft, pressure drop across orifice plates, and liquid levels in bubbler systems. Ideal for industrial, HVAC, and fluid amplifier systems, this differential pressure gauge ensures dependable performance in demanding environments.

• Accurate Measurements – ±2% full-scale accuracy at 70°F for precise fan, blower, and filter readings. Measures air/gas pressure in inWC (a standard HVAC unit), not liquid water.
• Versatile Applications – Perfect for measuring fan pressures, blower pressures, filter resistance, air velocity, furnace draft, and pressure drop across orifice plates.
• Durable Aluminum Construction – Built with aluminum for lightweight durability, suitable for air and compatible gases (excluding hydrogen).
• Precision Measurement Range – Accurately measures 0-0.5 inches of water, ideal for monitoring low air or non-corrosive gas pressures in a variety of systems.
• Dual Connections for Easy Setup – Equipped with 1/8-inch female NPT high and low-pressure taps, with duplicated side and back connections for flexible installation options.
