Air Velocity Meter, 0-23" w.c.
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 the 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 gauge fluid, and a carrying case.
Measure Both Pressure and Air Velocity
Read the red figures directly in feet per minute of velocity - from 400 to 10,000 fpm No conversion tables needed for air at standard conditions. Read the black figures in inches of water column air pressure - from 0 to 10" w.c.
Our most popular precision air velocity instrument, the No. 400 is used to balance air conditioning systems, measure the pressure drop across filters, and test fan and blower discharge and inlet pressures, as well as air velocity in ducts. It offers the convenience of a dual-purpose instrument - plus high accuracy on easy-to-read scales. The Series 400 includes "leveling" adjustment and glass bubble level, which makes it a versatile, all-around manometer for the air conditioning and balancing contractor or industrial plant.
