Dwyer 477AV-7 Digital Manometer, 0 to 100 psi

Model: 477AV-7

Features pressure, flow, and velocity measurements, along with a pressure range of 0 to 100 psi. The built-in air velocity and flow calculations provide accuracy and conserve time and error associated with manual calculations. The adjustable zero and span values allow for calibrating in the field, and damping compensates for the fluctuating of readings.
