Introduction
Congratulations on your purchase of the Extech 407112 Vane Anemometer. The 407112
measures air velocity in five units of measure: feet per minute (ft/min), meters per
second (m/sec), miles per hour (MPH), kilometers per hour (km/hr), & nautical miles per
hour (knots). The remote vane freely rotates in response to air flow. An internal
thermistor allows the 407112 to measures air temperature in centigrade or Fahrenheit
units. Careful use of this meter will provide years of reliable service.
