      Differential Pressure Gauge, 1/8"", FNPT, Gauge Connection Location: Back and Side These analog gauges help measure the difference in pressure on 2 inputs.

      Die-Cast Aluminum models are highly resistant to shock and vibration, and can be used to measure fan and blower pressure, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, and low air or gas pressure.

      Stainless Steel models are ideal for use where ambient corrosion is a concern. They offer excellent resistance to chemical, weather, and corrosion attacks.
