Differential Pressure Gauge JH Gauge 0-10 in H2O Aluminum 1/8 NPT

Description

Product Overview

The JH Gauge Differential Pressure Gauge is engineered for high‑precision measurement of low pressure differentials, ranging from 0 to 10 inches of water. Constructed from a solid aluminum body, the gauge balances durability with a lightweight profile, making it suitable for both portable and fixed installations. Its 1/8 NPT high‑ and low‑pressure taps on both sides and the rear provide flexible mounting options, while the 15 PSI full‑scale range ensures accurate readings across a variety of applications. The gauge operates reliably in ambient temperatures from 20 °F to 140 °F, delivering consistent performance in harsh industrial environments as well as controlled laboratory settings.

Usage

Designed for HVAC technicians, maintenance engineers, and fluid system specialists, this gauge excels in monitoring fan and blower pressures, filter resistance, and furnace drafts. It is equally effective for tracking pressure drops across orifice plates, validating fluid flow in pipelines, and ensuring proper operation of air handling units. Whether installed in a commercial building’s ventilation system, a manufacturing plant’s process line, or a research laboratory’s test rig, the gauge offers clear, repeatable readings that help users diagnose issues quickly and maintain optimal system performance.

Its compact dimensions (2.19 x 4.75 x 2.19 in) and lightweight design (1.2 lb) allow it to be mounted in tight spaces without compromising accuracy. The gauge’s robust construction resists corrosion and mechanical wear, making it a long‑lasting tool for routine inspections, preventive maintenance, and troubleshooting tasks across a wide temperature range.

FAQ

What is the maximum pressure this gauge can measure?

The gauge is rated for a full‑scale range of 15 PSI, which comfortably covers the typical low‑pressure applications found in HVAC, filtration, and fluid system monitoring.

Can this gauge be used in outdoor environments?

Yes. The aluminum construction and sealed NPT connections allow the gauge to operate outdoors, provided it is protected from direct exposure to rain or extreme weather conditions.

How do I calibrate the gauge for accurate readings?

Calibration should be performed using a known reference pressure source. Follow the manufacturer’s calibration procedure, ensuring the gauge is at a stable temperature (around 70 °F) for the most accurate results.

Is the gauge compatible with both metric and imperial pipe sizes?

The 1/8 NPT ports are standard in the United States, but adapters are readily available to connect to metric fittings, making the gauge versatile for international applications.

What warranty does JH Gauge provide?

JH Gauge offers a one‑year limited warranty covering manufacturing defects, along with access to technical support for installation and troubleshooting assistance.
