The Dwyer 2004D Magnehelic® Differential Pressure Gauge is a patented instrument engineered for precise measurement of air and non-combustible gases. It is an indispensable tool for critical pressure monitoring in HVAC systems, clean rooms, and hospital environments.
Key Specifications and Features:
– Operating Temperature: Operates effectively at a minimum temperature of 20 °F.
– Pressure Limits: Accurately measures pressures ranging from -20 inHg to 15 psig.
– Process Connection: Equipped with 1/8˝ female NPT duplicate high and low pressure taps for flexible installation.
– Housing: Features a robust die-cast aluminum case and bezel, secured with an acrylic cover. The exterior is finished with a coated gray layer, validated to withstand a 168-hour salt spray corrosion test for enhanced durability.
– Accuracy: Delivers reliable measurements with an accuracy of ±2%.
– Gage Movement: Incorporates Dwyer’s simple, frictionless Magnehelic® gage movement, providing quick indication of low air or non-corrosive gas pressures, whether positive, negative (vacuum), or differential.
