Product Description


The Extech AN100 can simultaneously display Air Flow or Air Velocity plus Ambient Temperature. Anemometers measure the speed (velocity) of moving air. Thermo-Anemometers also measure temperature by way of a thermometer located in the Anemometer sensor. The measurement units for Anemometers include: feet per minute (ft/min), meters per second (m/s), kilometers per hour (km/hr), miles per hour (mph), nautical miles per hour (knots), and Beauforts.
The large, easy-to-read backlit LCD includes primary and secondary displays plus numerous status indicators, including Data Hold and Min/Max. Capable of averaging up to 20 Air Flow or Air Velocity readings, the unit provides 3% velocity accuracy via low friction 2.83”D (72mm) ball bearing vane wheel on 3.9ft (120cm) cable. Easy-to-set area dimensions (cm2) are stored in the meter's internal memory for the next power on. It includes an auto power off function to conserve battery power.
Anemometers measure moving air with a rotary sensor which acts very much like a weathervane and can be likened to the blades of a fan. The vane freely rotates in response to air flow, and as the air moves through the vane the blades turn in proportion to the speed of the air.
Cubic Feet per Minute (CFM) or Cubic Meters per Minute (CMM) are units of measure for air volume measurements. This is a measurement of the quantity of moving air through an air duct, passageway, or enclosure. In order to determine this, the area of the duct must be measured. The area value (in ft2 or m2) is entered by the user, by pushbutton or keypad into the meter and an air velocity is determined.
