Model 166T Telescoping Stainless Steel Pitot Tube

Adjustable Design Extends Insertion Length to 36 Inches

The Model 166T Telescoping Pitot Tube is a unique air flow sensor which can quickly and easily be adjusted for any duct insertion length from 11.5 to 36 inches (29.2 to 91.4 cm). Now, this single compact unit can replace up to five conventional fixed length Pitot tubes. For even greater convenience, it is securely protected by a custom fitted polyethylene carrying case.
