Supco EM20 Digital Vane Thermo Anemometer, 0.4 to 20 m/s Velocity, -10 to +50° C Temperature

The Supco EM20 digital vane anemometer measures air velocity in m/s, fpm, knots, mph, km/h, and Beaufort scale, and air temperature in degrees C and F; and has maximum, minimum, and hold functions for analyzing air flow. Maximum and minimum function displays the highest and lowest readings since the meter was powered on or reset, and hold function freezes a reading on the display to aid documentation. The LCD shows velocity and temperature readings simultaneously and a backlight provides visibility in low light. The meter has an auto power-off mode that shuts it down after 20 minutes of non-use to conserve battery life and has a low-battery indicator. It has European Conformity (CE) marking. 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). Supco manufactures test instruments and replacement parts for heating, ventilation, air conditioning, and refrigeration systems. The company, founded in 1945, is headquartered in Allenwood, NJ.
