Series DP3 Differential Pressure Manometer

Wireless, Measures Differential Pressure, Air Velocity, and Flow

The Series DP3 Wireless Differential Pressure Manometer is a compact, highly accurate, auto-ranging differential pressure manometer ideal for low flow applications. The Series DP3 is used in conjunction with the Dwyer Mobile Meter® application software to view pressure drop across filters, static pressure in ducts, and velocity pressures from pitot tubes or air flow stations.
