Differential Pressure Gauge JH Gauge Aluminum Dual Tap 0-15 inH2O

Description

Product Overview

The JH Gauge differential pressure gauge is engineered to deliver reliable, accurate measurement of low‑pressure air and non‑corrosive gas streams. With a measurement range of 0‑15 inches of water (inH2O), it serves a broad spectrum of industrial, HVAC, and fluid‑system applications. Constructed from high‑grade aluminum, the gauge offers excellent resistance to corrosion and mechanical wear, ensuring a long service life even in demanding environments. The device features dual 1/8″ NPT pressure taps—one set positioned on the side and another on the back—providing flexible installation options for a variety of piping configurations. Its clear, easy‑to‑read dial is calibrated for a full‑scale accuracy of ±2 % at 70°F, and the gauge operates effectively across an ambient temperature range of 20°F to 140°F.

Usage

Designed for versatility, this differential pressure gauge excels in monitoring fan and blower pressures, filter resistance, and air velocity in ventilation systems. It is equally suitable for measuring furnace drafts, pressure drops across orifice plates, and fluid system pressure differentials. Installation is straightforward: connect the high‑pressure tap to the upstream side of the component under test and the low‑pressure tap to the downstream side. The gauge then displays the pressure differential, allowing technicians to assess performance, detect blockages, and schedule maintenance before failures occur. Its compact size and lightweight aluminum body make it ideal for both permanent installations in industrial plants and portable use by field service engineers.

FAQ

What types of fluids can be measured with this gauge?

The gauge is designed for low‑pressure air and non‑corrosive gases. It is not intended for high‑pressure liquids or aggressive chemicals.

How do I install the pressure taps?

Connect the high‑pressure tap to the upstream side of the component you wish to test and the low‑pressure tap to the downstream side. Use standard 1/8″ NPT fittings; no special adapters are required.

What is the accuracy of the gauge?

At a reference temperature of 70°F, the gauge provides an accuracy of ±2 % of full scale. Accuracy may vary slightly with temperature changes, but remains within specifications across the 20°F‑140°F range.

Can the gauge be used in outdoor installations?

Yes, provided the gauge is protected from direct exposure to rain or extreme weather. The aluminum housing offers good resistance to environmental factors, but a protective enclosure is recommended for harsh outdoor conditions.

What warranty does JH Gauge offer?

JH Gauge provides a one‑year limited warranty covering manufacturing defects. Technical support is available throughout the warranty period to assist with installation, calibration, and troubleshooting.
