Determine Air Velocity and Temperature Levels in Ducts or Air Supply Grills
The Series 471 Digital Thermo-Anemometer is the ideal portable product for determining air velocity and temperature levels in ducts or air supply grills. The 471-1's versatility is due to its four field selectable ranges from 0-500 FPM (0-3 MPS) up to 15,000 FPM (70 MPS). With a push of a button, FPM and Fahrenheit readings are converted to MPS and Celsius. Readings may be stored and retrieved which allows the user greater efficiency with HVAC balancing at various locations in a building. Model 471-2 has an extendable probe and model 471-3 provides a bendable extending probe for hard to reach sampling locations.
