The Dwyer® Magnehelic® gage is the industry standard for precise measurement of low air and non-corrosive gas pressures. Engineered for high accuracy, it reliably monitors fan and blower pressures, filter resistance, and furnace draft in critical industrial environments.
Key Specifications and Features:
– Precision Accuracy: Guaranteed within 2% of full scale, ensuring reliable and consistent pressure readings across the range.
– Broad Pressure Range: Standard models handle pressures from -20 inHg to 15 psig, with optional configurations extending maximum limits to 35 psig (MP) or 80 psig (HP) for specialized applications.
– Robust Operating Temperature: Designed for performance down to a minimum of 20 °F, maintaining operational integrity in diverse industrial settings.
– Standard Process Connections: Features 1/8˝ female NPT duplicate high and low pressure connections for straightforward integration into existing systems.
– Frictionless Measurement Mechanism: Incorporates Dwyer’s proprietary Magnehelic® gage movement for rapid, drift-free indication of positive, negative, or differential pressures.
– Extensive Model Selection: Available in a wide choice of 81 models to precisely match specific application requirements and pressure ranges.
