Learn More: http://www.tequipment.net/Dwyer/477AV... The Dwyer 477AV Handheld Digital Manometer is available with pressure, flow, and velocity measurements along with a number of other features. The 477AV uses a highly accurate differential pressure sensor to offer ± 0.5% full scale accuracy. It displays negative, positive, and differential pressure. For pressure, flow, and velocity there are selectable English and metric units, as seen in the model chart below. The built-in air velocity and volumetric flow calculations conserve time associated with cumbersome manual calculations. Additionally, up to 40 readings can be saved—perfect for HVAC technicians making Pitot tube traverses of airflow readings across a duct. The accuracy that the 477AV Series provides is critical to maintenance personnel and technicians who require a highly accurate standard to check their instrumentation or equipment, to ensure proper performance.
