Fluke 922 Airflow Meter/MicromanometerThe Fluke 922 makes airflow measurements easy by combining three tools: differential pressure, airflow, and velocity into a single, rugged meter. With performance, ruggedness, and ease of use, the Fluke 922 is set apart from the competition. The bright white display and ruggedized holster and wrist strap let users take the Fluke 922 into less than ideal environments. The color coded hoses help keep track of where readings are coming from.
