The DM4770AV 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.

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

Stores up to 40 readings with minimum, maximum and average statistics

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.
Unfortunately, we do not have any manometers available that can handle chlorine gas or sodium hydroxide (bleach).
