The Dwyer 2302 (HB202) Magnehelic® Gage is a highly accurate differential pressure gauge designed for demanding industrial and HVAC applications. It provides precise measurements of pressure, vacuum, or differential pressure in air and non-corrosive gases, offering exceptional durability and maintenance-free operation.
Key Specifications and Features:
– Accuracy: Guaranteed high accuracy within ±2% of full scale (±3% on -0, -100 Pa, and -60 Pa ranges) for dependable readings.
– Scale Design: Features an accurate, easy-to-read litho-printed scale combined with a highly visible red-tipped pointer for clear indication.
– Movement Mechanism: Equipped with shock-resistant jeweled bearings, ensuring smooth, friction-free pointer movement and enhanced longevity.
– Durability and Resilience: Engineered to withstand shock, vibration, and over-pressure conditions, providing robust performance in harsh environments.
– Maintenance-Free Operation: Designed without manometer fluid, eliminating issues such as evaporation, freezing, toxicity, or leveling problems associated with traditional fluid manometers.
– Pressure Limits: Standard operational range from 20 in Hg vacuum to 15 psig (-0.677 bar to 1.034 bar). Specialized MP (Medium Pressure) options extend limits to 35 psig (2.41 bar), and HP (High Pressure) options to 80 psig (5.52 bar).
– Housing Construction: Constructed with a durable die-cast aluminum case and bezel, complemented by an acrylic cover for standard models, while MP models feature a robust polycarbonate cover.
