Dwyer 2300-100Pa Magnehelic Differential Pressure Gauge

Product Introduction

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.

Product Features

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 <35 psi).

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.
