The 2000 Series Magnehelic differential pressure gauges offer unparalleled versatility and reliability, featuring 81 selectable ranges with an accuracy of up to 2%. Leveraging a wear-free, magnetic movement mechanism, these gauges provide rapid and sensitive readings for low positive pressure, negative pressure, or differential pressure of gases.

Engineered with shockproof and overpressure protection, they eliminate common issues like liquid evaporation, freezing, and horizontal calibration requirements found in traditional liquid-filled gauges. Economical and user-friendly, Magnehelic gauges are the ideal choice for a wide array of applications, from industrial monitoring to medical equipment.

• Precision & Range: 81 ranges available with ±2% full-scale accuracy (varies per model), ensuring tailored performance for diverse needs.
• Wear-Free Design: Magnetic movement eliminates mechanical friction, enhancing durability and reducing maintenance.
• Versatile Pressure Measurement: Instantly detects low positive, negative, or differential pressures of air and compatible gases.
• Robust Protection: Built-in shockproofing and overpressure relief (standard models release at 25 psig) safeguard against damage.
• Cost-Effective: Affordable pricing combined with hassle-free operation and long lifespan.
• Liquid-Free Operation: Avoids liquid-related failures, simplifying installation and use.

• Industrial Ventilation: Monitor fan outlet static pressure, filter resistance, and wind speed.
• Process Control: Measure differential pressure across orifice plates and liquid level in blowing systems.
• HVAC Systems: Assess ventilation status and air handling efficiency.
• Medical & Scientific: Monitor gas-air mixing ratios, respiratory pressures, and equipment performance.
• Specialty Use: Suitable for hydrogen applications with Buna-N nitrile rubber diaphragm (pressure ≤ 35 psi).
