Digital Thermo-Anemometer Telescoping Bendable Tip, Four Selectable Ranges, ±3% Full Scale Accuracy

The Model 471-3 Digital Thermo Anemometer now features a telescoping bendable tip for easy access in hard-to-reach locations. The Model 471-3P is a versatile dual function instrument that quickly and easily measures air velocity in four field selectable ranges - feet per minute or meters per second - plus air temperature in °F or °C. High contrast LCD display shows both range selected and present velocity. Convenient backlight provides perfect visibility in low light conditions. Light automatically shuts off after 2 1/2 minutes to prolong battery life. Low battery warning is included. Extruded aluminum housing fully protects electronics, yet is lightweight and comfortable to hold even when taking multiple readings as part of duct traverses. Stainless steel probe with comfortable hand grip. When fully extended, the model 471-3 reaches 33 inches (83 cm). Standard accessories are 9 volt alkaline battery, wrist strap, custom fitted carrying case and step drill for making duct holes from 3/16" to 1/2".
