Read the red figures directly in fpm of velocity—from 400 to 10,000 fpm.
Read the red
figures directly in fpm of velocity—from 400 to 10,000 fpm. No
conversion tables needed for standard condition. Read the black figures
in inches of water column. Air pressure—from 0 to 10" W.C.
Our most popular
precision air velocity instrument. This meter is used to balance air
conditioning systems, measure pressure drop across filters and test fan
and blower discharged 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. A versatile, all around manometer for
the air conditioning and balancing contractor or industrial plant.
