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.
