The Dwyer 660 air velocity monitor monitors air flow in laboratory fume hoods. A constant temperature thermistor measures airflow and three colored LED lights indicate airflow level; red indicates low airflow, yellow indicates high airflow, and green indicates normal airflow. An audible alarm warns the user when airflow is low and requires manual resetting. The mounting holes fit a standard single-gang electric box and connect to the interior sidewall using 1-1/8" flexible tubing.

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).

Dwyer Instruments manufactures measurement and control instruments, including pressure gauges, flow meters, level instrumentation, temperature instrumentation, and air quality monitors. The company, founded in 1931, is headquartered in Michigan City, IN.
