The Kanomax 6700-06 is a stainless steel pitot tube with 5/16" (diameter) x 48-5/8" (insertion length). This pitot tube is constructed from corrosion-resistant stainless steel with permanently etched insertion depth graduations for a lifetime of service. It monitors air velocity or air flow when used with our micromanometer. The static pressure port is parallel to the sensing tube to allow quick, easy alignment of the tube with airflow.
