The Kanomax TABmaster is a capture hood for accurate supply and return airflow measurements. The unit features a 23 to 2500 cfm (40 to 4250 m3/h) range; simultaneously measures and displays airflow, temperature, and humidity; and displays the direction of the airflow, as well as the velocity. Five optional hood sizes make it easy to pick one that fits any duct, while the built-in back pressure compensation helps ensure accuracy for large volumetric flow measurements.
