Be the first to review this product

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

FAQ

Questions

Question

We use series 477AV digital manometer. What is the recommended calibration interval?

Answer

We do not have an official recommended calibration interval. However, we would suggest checking the calibration at least once or twice a year depending on the application and how often the unit is used.
