400 Air Velocity Meter

Displays Velocity and Air Pressure

The Series 400 Air Velocity Meter offers the convenience of a dual purpose instrument with high accuracy and easy-to-read scales. It can be used to balance air conditioning systems, measure pressure drop across filters, and test fan and blower discharge and inlet pressures. Series 400 kits include a manometer, Pitot tube, necessary tubing and connectors, red gage fluid, and carrying case.

Kit includes No. 400 Air Meter and all accessories:

Combination Inclined/Vertical Manometer. Dwyer® Durablock® precision machined solid acrylic plastic construction is virtually indestructible. Has both inclined section for high accuracy and vertical section for extended range. Pressure marked in black, Velocity in red figures. Easy to read - no reference tables needed. Has screw leveling adjustment and ground glass bubble level.
