Differential Pressure Gauge 0-1 Inches of Water, Aluminum, 1/8" Female NPT Taps, Accurate to 2%, Measures Air Pressure, Filter Resistance, Furnace Draft & More

The Differential Pressure Gauge (0-1 inches of water) is an essential tool for measuring low air or non-corrosive gas pressures, both positive and negative (vacuum), as well as differential pressure in a variety of industrial, HVAC, and laboratory applications. Perfect for measuring fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems, and pressures in fluid systems, this gauge provides accurate and reliable readings. Constructed from durable aluminum, this gauge is designed for long-lasting use and boasts a pressure rating of 15 PSI and an accuracy of ±2% of full scale at 70°F. It features 1/8” female NPT high and low-pressure taps for easy connection and quick installation, making it an ideal choice for systems using air or compatible gases. The temperature range of 20°F to 140°F ensures reliable performance across a wide range of environmental conditions. This differential pressure gauge is indispensable for applications such as filter monitoring, fan performance measurement, HVAC system diagnostics, and liquid pressure measurements in systems like fluid amplifiers or industrial machinery. Please note: this gauge is not for use with hydrogen gas.

• Versatile Pressure Measurement: Ideal for measuring both positive, negative, and differential pressures in air or compatible gases, making it perfect for fan and blower pressures, air velocity, and filter resistance applications.
• 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.
• Durable Construction: Made from aluminum, this differential pressure gauge is built for durability, providing long-lasting use even in demanding environments, and offers a 15 PSI pressure rating for robust performance.
• Flexible Installation: Features 1/8” female NPT high and low-pressure taps, with duplicated taps (one pair on the side and one on the back), allowing for versatile installation options in various setups.
• Wide Temperature Range: With an ambient temperature range of 20°F to 140°F, this gauge is suitable for a variety of applications, including HVAC systems, fluid amplifiers, furnace drafts, and more.
