Featuring a large 4-inch dial, Β±2% accuracy, and a rugged aluminum case, it delivers reliable, maintenance-free performance with silicone fluid damping and a shock-resistant design. Ideal for HVAC, fluidic systems, and industrial applications, it ensures precise pressure readings with easy installation and long-term 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.

Sin problemas. ### ⭐⭐⭐⭐⭐ Great gauge *by C***Y on January 21, 2026* Very accurate gauge ### ⭐⭐⭐⭐⭐ Works for HVAC Filter Gauge *by R***M on August 16, 2021* This is the second I purchased. This unit has lower range needed to fit my needs. I use this to determine filter changes on my HVAC. Once the pressure increases by say 15 to 20 percent I change the filter. This allows me to keep the static pressure below 0.60 IWC specified in the installation of my air handler. ## Frequently Bought Together - Dwyer 2002 Magnehelic Differential Pressure Gauge, Type, 0 to 2" WC - Dwyer 6846277 Portability Kit for Magnehelic Gauges - Fieldpiece ASP2 Static Pressure Probes --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/41747091-dwyer-2002-magnehelic-differential-pressure-gauge-type-0-to-2](https://www.desertcart.vu/products/41747091-dwyer-2002-magnehelic-differential-pressure-gauge-type-0-to-2) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-14*
