The Thomas Traceable Digital Anemometer with vane probe measures air velocity in m/s, fpm, knots, and km/h, and air temperature in degrees C and F; and has a hold switch that freezes a reading on the display to aid documentation. The vane probe has a 4-ft. cable for reaching into ductwork. A bench stand is built into the back of the meter for viewing readings on the 3-1/2 digit LCD. The meter includes a calibration certificate from an International Organization for Standardization (ISO) 17025 laboratory accredited by the American Association for Laboratory Accreditation (A2LA) with traceability to National Institute of Standards and Technology (NIST) standards. This anemometer is used for monitoring air flow and temperature in ductwork, spray booths, and exhaust hoods, among other applications.
|Air velocity range||0.4 to 30.0 m/s; 80 to 5,910 fpm; 0.8 to 53.3 knots; 1.4 to 108.0 km/h|
|Air velocity resolution||0.1 m/s; 10 fpm; 0.1 knots; 0.1 km/h|
|Air velocity accuracy||+ or - (2% + 1 digit)|
|Air temperature range||0.0 to 60.0 degrees C/32.0 to 140.0 degrees F|
|Operating environment||0 to 50 degrees C/32 to 122 degrees F at less than 80% relative humidity|
|Power||(1) 9V battery (included)|
|Main unit dimensions (H x W x D)||6-1/4 x 3 x 1-1/4 inches|
H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.
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).
