Series 471

Digital Thermo Anemometer Four Air Velocity Ranges to 0-15,000 FPM, 0-70 MPS, ±3% Full Scale Accuracy, Low in Cost, Temperature Measruement to 200°F, 100°C, Max. 33 Inches (83 cm) Adjustiable Telescoping Tip

The Model 471-1 Digital Thermo Anemometer is a versatile dual function instrument which 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 broth range selected and present velocity. Convenient backlight provides perfect visibility in low light provides perfect visibility in low light conditions. Light automatically shuts off after 2 ½ 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 is etched with insertion depth marks from 0-8 inches and 0-20 cm. An integral sliding cover protects sensors when not in use. Standard accessories are 9 volt alkaline battery, wrist strap, custom fitted carrying case and step drill for making duct holes from ³/₁₆" to ½".
