Handheld Thermal Anemometer- Series 470-1

The versatility of the Dwyer 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 provides two switch selected air velocity ranges of 0-600 FPM and 500-6000 FPM displayed on an easily read analog meter. Two standard 9 volt alkaline batteries provide eight hours of operating time (equivalent to over 5000 readings) and a convenient LED low-battery indicator avoids lost time on the job when battery replacement is required. Sophisticated temperature compensation circuitry maintains ±5% of full range accuracy over an air stream temperature of 30°F to 180°F. Secured by means of a wrist strap and held in either the right or left hand, the indicating unit provides easy one hand access to the range switch, zero adjust, and the push-to-measure switch. The opposite hand is free to insert the stainless steel probe into ducts up to a depth of 8" with probe insertion depth indicated by means of a scale etched on both sides of the probe body. The 1 foot coiled probe cord stretches to 5 feet for both convenient storage and operation. The spring return push-to-measure switch turns the unit off automatically after each reading to prevent unnecessary battery drain. The Model 470-1 Thermal Anemometer comes complete with a durable polypropylene, foam-lined carrying case with full operating instructions provided on the inside of the case lid.
