Dwyer 471B Thermo-Anemometer

The Dwyer 471B Digital Thermo Anemometer is a versatile dual function instrument that quickly and easily measures air velocity or volumetric flow plus air temperature in imperial or metric units. The 471B includes a high contrast LCD display which shows both selected readings simultaneously. A convenient backlight, which automatically shuts off after 2-1/2 minutes to prolong battery life, provides perfect visibility in low light conditions. The stainless steel probe has a comfortable hand grip and is also etched with insertion depth marks from 0 to 8 inches and 0 to 20 cm. Extruded aluminum housing fully protects electronics, yet is lightweight and comfortable to hold even when taking multiple readings as part of duct traverses. Up to 99 readings may be stored for later retrieval. An integral sliding cover protects sensors when not in use.
