The Dwyer 477AV-7 Handheld Digital Manometer is now available with pressure, flow, and velocity measurements along with a number of other convenient features. The built-in air velocity and flow calculations provide accuracy and conserve time and error associated with manual calculations, and have a velocity range of 210.7k fpm (1070 m/s). Also featured on the 477AV7 are adjustable zero and span values for calibrating in the field, as well as a damping feature to compensate for the fluctuating of readings.
