Standard 5/16" Diameter Pitot Tubes

• Recommended for ducts 10" and larger in diameter. The plainly inscribed inch graduation show depth of insertion on both sides at a glance. This helps you find the exact center of any duct and makes an accurate traverse quickly. The tubes comply with AMCA and ASHRAE specifications and have test-confirmed unity coefficients. The lifetime construction is of No. 304 Stainless Steel, and the tubes are suitable for use in temperatures up to 1500šF. Readings are accurate when the tip is directed within 15š of air flow direction. Static connection extends 3 1/2" to serve as a guide for the directing tip which is swaged and has silver soldered connections. The tubes come in 7 sizes from 8" to 60" long (up to 216" long with larger diameter) 

Pocket-Size 1/8" Diameter Pitot Tubes

Recommended for ducts 4" and larger in diameter. They are geometrically scaled down per AMCA code and have a unity coefficient design. A springy, No. 304 grade stainless steel hypodermic needle withstands flexing without damage and resists temperatures up to 800šF. The extended static connection serves as a guide for directing tip into air stream. They are of silver soldered quality construction and suitable for permanent mounting in OEM applications. There are four models - 6" or 12" lengths in standard or short tip styles.
