Dwyer Instruments Magnehelic 0-50 Inches Of Water Gauge 2050

The Dwyer Instruments Magnehelic® Differential Pressure Gauge, model 2050, is a precision instrument engineered to measure low differential pressures of air and non-combustible, compatible gases. With a measurement range of 0 to 50 inches of water column (in. w.c.), it is ideal for applications such as monitoring fan and blower pressures, filter resistance, air velocity, furnace draft, and pressure drops across orifice plates.

Key Features

• Large, Easy-to-Read Dial: The 4-inch (102 mm) dial provides clear and accurate readings, facilitating quick assessments of pressure conditions.
• Frictionless Movement: Utilizing Dwyer’s simple, frictionless Magnehelic® gauge movement, it quickly indicates positive, negative (vacuum), or differential pressures without the need for manometer fluids.
• Durable Construction: The gauge features a die-cast aluminum case and bezel with a gray-coated, corrosion-resistant finish, ensuring longevity and resistance to shock, vibration, and over-pressure.
• Weatherproof Design: Rated IP67, the housing is designed to withstand harsh environmental conditions, making it suitable for various industrial applications.
• Easy Zero Adjustment: A conveniently located zero adjustment screw on the plastic cover allows for easy calibration without removing the cover.
