Along with many other useful features, the Series 477AV Handheld Digital Manometer now comes with measures for pressure, flow, and velocity. Accuracy, time savings, and reduced error associated with human calculations are provided by the integrated air velocity and flow computations. This device also includes a damping feature to account for reading fluctuations and configurable zero and span values for field calibration.
