Dwyer Instruments 2301 Magnehelic Differential Pressure Gauge 0.5" To 0" - 0.5" WC

The Dwyer Instruments 2301 is a compact and dependable differential pressure gauge that is used in HVAC systems to monitor minor air or non-corrosive gas pressure variations. It uses a magnetic movement, which makes it resistant to shock, vibration, and overpressure, in contrast to conventional liquid-filled gauges. It is perfect for monitoring air filters, blowers, fans, and duct pressure in a variety of HVAC applications since it monitors pressures between -0.5 and 0.5 inches of water column (w.c.).The gauge provides an easy and affordable alternative because it doesn't require energy to function. It has a zero adjustment screw that is easily situated, a pointer that stops at the end of the scale to prevent damage, and a transparent plastic face for easy viewing.
