Series 477AV Handheld Digital Manometer

Measures Pressure, Flow and Velocity; ±0.5% Accuracy

The Series 477AV 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. Also featured on this unit are adjustable zero and span values for calibrating in the field, as well as a damping feature to compensate for the fluctuating of readings.

NIST CALIBRATION available in Product Configurator.

Product Applications

Air flow monitoring, when used with a Dwyer® pitot tube
Duct static pressure
Commercial air balancing
Building-zone pressure

Calculates and displays air velocity and volumetric air flow
Rugged aluminum case protects instrument from damage during transport/use
9 selectable English and metric engineering units
Large, easy to read display with backlight for use in dark areas
