Digital Manometers

The 477AV series offers pressure, flow, and velocity measurements. The built-in air velocity and flow calculations provide accuracy and conserve time and errors. Additionally, it features adjustable zero and span values for calibrating in the field, as well as damping to compensate for the fluctuating of readings.

Measures positive, negative, or differential pressure of air and natural gases in ranges from 1 "w.c. (0.249 kPa) to 150 psid (10.34 bar). The dual push pads on the front panel control the on/off, auto-zero, and pressure unit selection, allowing for simple operation with no set up needed.
