The Energy Conservatory introduces an improved DG-700 Pressure and Flow Gauge, which evaluates the air tightness of homes and small commercial buildings. The DG-700 Pressure and Flow Gauge is a multi-functional differential gauge with two independent measurement channels. This is ideal for a wide range of building performance testing applications including air tightness testing, exhaust fan flow measurement, air handler flow measurement, building pressurization and combustion safety testing, as well as static pressure and velocity measurements using a Pitot tube.
