The Dwyer 160F-KIT Pitot Tubes kit with carrying case is ideal for use with Dwyer precision air velocity gauges, transmitters and digital test instruments. The 160FKIT pitot tubes are constructed from corrosion resistant stainless steel for a lifetime of service. Permanent, stamped insertion depth graduations on sides of the Pitot tubes facilitate accurate positioning. Static pressure ports are parallel to sensing tube allowing quick, easy alignment of tubes with the 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. The pitot tubes come in lengths of 60", 48", 36", 24", and 18".
