Dwyer 471-3 Digital Thermo Anemometer The Series 471 Digital Thermo Anemometers are versatile dual function hand-held battery operated instruments that quickly and easily measure air velocity in four field selectable ranges – feet per minute (FPM) or meters per second (MPS) – plus air temperature in °F or °C. High contrast LCD display shows both range selected and present velocity.  The Model 471-3 probes extend to 33 inches (83cm). The probe tip on the Model 471-3 is bendable up to 90 degrees in any direction for easy access in hard-to-reach locations. A 7 /16? (111 mm) hole is required for full probe insertion. When extending or collapsing the tip, be sure the connecting cable moves freely through the opening at the base of the handle. For optimum accuracy, be sure to extend the tip a minimum of 21 /2? (6.36 cm) for all measurements.  Also note that the two openings in the tip must be parallel to air flow for best accuracy. A convenient way to assure proper alignment when tip is out of view (such as inside a duct) is to note the orientation relative to the handle before insertion. Item worked when put into storage ~4-5 years ago. Sold as-is.
