The Series 160F stainless steel pitot tubes have permanent, stamped insertion depth graduations on the sides of the tube facilitate accurate positioning while taking a duct traverse. The static pressure port is parallel to the sensing tube providing quick, easy alignment of sensor with air flow. The straight design allows for easy insertion into ducts through grills and pressure taps, as well as aids in positioning in hard to reach locations where a hook style Pitot tube may not allow access.
