The Dwyer 473B-1 vane thermo-anemometer is a handheld unit that can measure air velocity or volumetric flow, air temperature and humidity using a stainless steel 100mm vane probe (included). The 8″ probe is paired with a 28″ retracted cable that can be extended up to 6-feet in length. Designed for use with clean, dry air the Dwyer 473B-1 is an ideal solution for residential balancing and HVAC inspections.
The 473B-1 can measure process temperatures between -20 to 212°F and from 0 to 100% relative humidity. Additionally, air velocity can be measured from 40 to 5000 fpm and volumetric air flow up to 19,999 in selected flow units. Using a 4.5 digit backlit display, this Dwyer vane thermo-anemometer clearly displays data for real-time readings and can also store up to 99 readings for later evaluation.
