Model 470-1

The versatility of the Model 470-1 Handheld Thermal Anemometer makes it ideal for a wide range of air velocity measurements. Easy to carry and use in the field, the 470-1 can be used to balance heating and air conditioning systems, measure velocity in HVAC ducts, read fume and exhaust hood face velocities, as well as make wind speed measurements associated with agricultural, forestry, highway and recreational activities. This low cost battery powered electronic instrument features an LED low-battery indicator and provides two switch selected air velocity ranges of 0-600 FPM and 500-6000 FPM displayed on an easily read analog meter.

Sophisticated temperature compensation circuitry maintains ±5% of full range accuracy over an air stream temperature of 30 to 180°F. Included are two 9 volt alkaline batteries, a wrist strap for the unit and a durable polypropylene, foam-lined carrying case.
