Dwyer 160 Series Pitot Tubes

Dwyer 160 series pitot tubes are constructed from corrosion resistant stainless steel for a lifetime of service. Ideal for use with precision manometers and air velocity gauges, 160 series pitot tubes feature ASME design to meet AMCA and ASHRAE specifications for maximum accuracy over a wide variety of flow conditions. No correction factors required as ASHRAE tip design yields a calibration factor of 1. ASHRAE design needs no calibration! Permanent, stamped insertion depth graduations on sides of 160 series facilitate accurate positioning. Static pressure port is parallel to sensing tube allowing quick, easy alignment of tube with air flow. Low sensitivity to misalignment gives accurate reading even when tube is misaligned up to 15 degrees. Various standard sizes are available for use in ducts as small as 4" in diameter or as large as a 36 ft. diameter. A universal model fits user supplied 3/4" schedule 40 (standard) pipe in any length. Several convenient mounting options are available for permanent installations.
