Description
|
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.
