The efficient operation of your school’s fume hood is essential to the well-being of you and your students. Used to check fume-hood efficiency, a velometer measures air velocity with readings expressed as linear feet of air per minute. To check hood efficiency, measure the air velocity at the “face” of the hood opening, ideally at multiple locations across the face. A hood should provide air movement of at least 100 linear feet of air per minute. Easy to use, the device must be level during use so a bubble level is built in. The unit is calibrated from 0 to 400 feet per minute. Accuracy is ±10%, full scale. A carrying case is available separately to protect the instrument during storage or enable you to transport the unit safely from hood to hood or school to school.
