| Dwyer Digital Thermo-Anemometer 471 (#471-B) | $18.75 | $43.78 | $125 |
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 high-contrast LCD display shows both selected readings simultaneously. A convenient backlight provides perfect visibility in low-light conditions and automatically shuts off after 2-1/2 minutes to prolong battery life. The stainless steel probe is etched with insertion depth marks from 0 to 8 inches and 0 to 20 cm. The 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.
