The Reed 8906 vane anemometer measures air velocity in m/s, fpm, knots, mph, and km/h and air temperature in degrees C and F; calculates air flow volume; and has digital functions including single-point and multi-point average for analyzing air flow. When the dimensions of the area being measured are keyed in, the meter can calculate and display air flow volume in cfm. Single-point function records and displays minimum and maximum readings and can display a continuous moving average of air velocity for up to two hours. Multi-point average function records up to eight readings and displays the average value. The hold function freezes a reading on the display to aid documentation of readings. An RS-232 serial port interface output allows connection to a compatible PC for storing data (interface cable sold separately). The four-digit LCD readout shows air velocity and temperature readings simultaneously. It operates on a single 9V battery (included), turns off automatically after 20 minutes of non-use to conserve battery life, and has a low-battery indicator. This anemometer is used for monitoring air flow and temperature in ductwork, spray booths, and exhaust hoods, among other applications.

Anemometers, also called wind meters, measure air velocity and are most commonly used for weather monitoring to determine wind speed and for HVAC applications to determine air flow within ducts. In addition to air velocity, anemometers may measure wind direction, air pressure, air flow volume, air temperature, humidity, light, and other properties. The most common types of anemometer are cup, vane, hot-wire, and Pitot tube. Cup and vane anemometers calculate air velocity based on the number of rotations of the cups or vane. Hot-wire anemometers calculate air velocity by measuring the change in electrical resistance as air flow cools a heated wire. Pitot tube anemometers measure air pressure within a tube and calculate air velocity based on the difference in pressure between the air inside and outside of the tube. Many anemometers have digital readouts and can display air velocity readings in different units of measure, such as meters per second (m/s), feet per minute (ft./min. or fpm), knots, miles per hour (mph), and kilometers per hour (km/h).
