The Testo 410-1 vane anemometer measures air velocity in m/s, fpm, knots, mph, km/h, and Beaufort scale and air temperature in degrees C and F; calculates windchill temperature; and has hold, maximum, minimum, and timed mean calculation functions for analyzing air flow. Hold function freezes a reading on the display to aid documentation, maximum and minimum functions display highest and lowest readings since the meter was powered on or reset, and timed mean calculation function displays an average reading over time. The meter includes a calibration certificate. The LCD shows air velocity and temperature measurement simultaneously and a backlight provides visibility in low light. The unit has an auto-off mode that shuts it down after 10 minutes of non-use to conserve battery life and has a low-battery indicator. A wrist strap provides a secure hold during one-hand operation. This anemometer is used for weather monitoring and for checking air flow and temperature in ductwork, spray booths, and exhaust hoods, among other applications.

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).
