Differential Pressure Gauge, 0-20 Inches of Water, Aluminum Construction, ±2% Accuracy, 1/8 Inch Female NPT, 15 PSI, for Air & Gas Applications

This Differential Pressure Gauge is designed for accurate measurement of low air or non-corrosive gas pressures, making it an essential tool for HVAC systems, industrial processes, and laboratory applications. Capable of measuring both positive, negative (vacuum), and differential pressures, this gauge is ideal for monitoring a range of systems such as fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, and liquid levels in bubbler systems. Built with precision in mind, this gauge features a robust aluminum body with 1/8-inch female NPT connections, allowing it to be integrated into a variety of systems. The gauge offers an impressive accuracy of ±2% at 70°F, ensuring reliable and consistent readings. With a pressure rating of 15 PSI and an ambient temperature range from 20°F to 140°F, this gauge is perfect for use in air and gas applications where precise pressure monitoring is required. Its liquid-filled glycerin design minimizes the effects of vibrations, enhancing the longevity and accuracy of the gauge.

• Wide Measurement Range: Measures pressures from 0 to 20 inches of water, suitable for low-pressure applications involving air and non-corrosive gases.
• Durable Construction: Made of aluminum for lightweight yet robust durability, built to withstand long-term use in industrial, HVAC, and laboratory settings.
