## Overview

The Dwyer 2002 Magnehelic Differential Pressure Gauge delivers precise measurement of low air and gas pressures from 0 to 2 inches of water column. Engineered with a rugged, shock-resistant design and silicone fluid damping, it ensures reliable, maintenance-free operation. Featuring a large 4-inch dial and easy zero adjustment, it’s the go-to gauge for HVAC professionals and fluid system managers seeking trusted accuracy and durability.

## Description

The Magnahelic guage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems, and pressures in fluid amplifier or fluidic systems. The gauge's motion is damped with high-viscosity silicone fluid. The zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness. Rugged design resists shock, vibration, and overpressure. The helix is precision-made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the maganetic field to move the pointer across the scale. The samarium cobalt magnet is mounted at one end of the range spring and rotates the helix without mechanical linkages. The industry standard in indicating low air or gas pressures of positive, negative, or differential pressures Large, easy-to-read 4" (102 mm) dial. No manometer fluid to evaporate, freeze, or cause toxic or leveling problems

Review: 0ne out off five units arrived without the accessory bag and the magnehelic is not in the plastic casing. I guess could be as a result of irresponsible inspection
Review: The gauge itself is great but when I received item it was missing the barbed fittings and all other contents.
