Low flow balometer for measuring very low volumetric flow in residential and light commercial applications. The measurement range is from 10 to 500 cfm. The compact size allows it to be used where full size hoods would not fit such as over bathroom stalls or filing cabinets. Comes with a 2' x 2' tall flow hood and 18" x 18" short flow hood. The unit can be used without the flow hoods in tight measurement locations.
