Dwyer Magnehelic® Gage – Overview & Specifications
The Dwyer Magnehelic® Series 2000 measures low differential pressure without requiring power, using a frictionless mechanical movement for high repeatability. Ideal for HVAC applications, it supports air velocity, blower vacuum monitoring, fan pressure indication, and more.
Key Technical Details
- Accuracy: ±2% of FS (High Accuracy option: ±1%)
- Dial Size: 4 in (102 mm)
- Mounting: Vertical diaphragm
- Pressure Range: -20 inHg to 80 psi
- Enclosure: IP67 weatherproof
- Connection: 1/8" NPT female, side and back pairs
- Materials: Die cast aluminium case, acrylic cover
- Weight: 510 g
- Compatible Media: Air, argon, CO₂, helium, nitrogen, non-corrosive dry gases
- Safety Features: Relief plug opens at 25 psig for standard models
Available in 81 models and 27 configuration options, including High Accuracy (-HA) models with mirrored scale and 6-point calibration.
Benefits & Features of the Series 2000 Magnehelic® Gage
The Series 2000 Magnehelic® is a dependable workhorse for professionals monitoring low differential pressure in commercial buildings, cleanrooms, labs, and industrial HVAC systems. Its virtually friction free motion enables smooth and consistent readings, even in demanding environments.
Engineered for long-term reliability, the design resists shock, over-pressures, and vibration, while the die cast aluminium case and IP67 enclosure ensure pressure integrity. The high viscosity silicone fluid dampens movement and stabilises readings.
Key features include:
- Zero adjustment screw for easy calibration
- Range spring rotates helix with minimal wear
- Silicone rubber diaphragm for responsive, accurate readings
- Adjustable signal flag for visual threshold marking
- Flat spring steel and molded rubber prevent pointer flutter
Whether integrating into a smart building system or maintaining airflow compliance in a hospital, the Magnehelic gauge offers performance and peace of mind. Compatible with Dwyer Pitot Tubes for air velocity measurement and scalable for future retrofits.

Frequently Asked Questions
What’s the difference between a standard and high-accuracy Magnehelic®?
The High Accuracy (-HA) model provides ±1% full-scale accuracy (vs. ±2% on standard), a mirrored dial, and 6-point calibration certificate. It’s ideal for cleanrooms and room positive pressure indication.
Can the Magnehelic® gage be used outdoors?
Yes. The IP67 enclosure rating and die cast aluminium case make it suitable for outdoor or industrial environments where pressure integrity and weatherproofing are critical.
Is the Series 2000 suitable for hydrogen?
Yes, but only with a Buna-N diaphragm and under 35 psi. Always consult Controls Traders to ensure material compatibility and safety in such applications.
Does this gage require electrical power?
No. The Series 2000 Magnehelic® is a mechanical differential pressure gauge that operates without power, perfect for temporary sites or backup monitoring in isolation environments.
How do I use the gage for filter monitoring?
Install the Magnehelic gage across the filter to monitor differential pressure. An increasing reading signals filter clogging. Use the adjustable signal flag to mark the maintenance threshold.
