The Dwyer 2300-100Pa Magnehelic Differential Pressure Gauge is a high-accuracy instrument designed for precise measurement of low air and non-corrosive gas pressures. With an accuracy guarantee of ±2% of full scale, this gauge leverages Dwyer's frictionless magnetic movement to quickly indicate positive, negative (vacuum), or differential pressures.

Its rugged design resists shock, vibration, and overpressure, while eliminating fluid-related issues like evaporation or freezing. Ideal for industrial and medical applications, the 2300-100Pa model is part of Dwyer's industry-standard Magnehelic series, offering reliable performance for fan pressure monitoring, filter resistance measurement, and more.

• High-Accuracy Measurement: ±2% of full-scale accuracy at 70°F (21.1°C), ensuring precise pressure readings. 100Pa measurement range suitable for low-pressure applications.
• Frictionless Magnetic Technology: Dwyer's Magnehelic movement eliminates mechanical friction for consistent, drift-free performance.
• Robust Environmental Resistance: Withstands shock, vibration, and overpressure (relief plug opens at ~25 psig for standard models). Die-cast aluminum housing with gray coating passes 168-hour salt spray test.
• Versatile Pressure Types: Measures positive, negative (vacuum), or differential pressures in air and non-combustible gases. Optional Buna-N diaphragm for hydrogen applications (pressures
• Low-Maintenance Design: No manometer fluid to evaporate, freeze, or cause toxicity/leveling issues.
• Wide Application Range: Industrial: Fan/blower pressure, filter resistance, air velocity, furnace draft. Medical: Blood and respiratory pressure monitoring in healthcare equipment.
