Digital vane anemometer provides an accurate and affordable way of measuring air velocity, volume flow, temperature, and relative humidity in a number of different combinations. Air velocity is measured in either metres per second or feet per minute. Readings for average, maximum and minimum velocity can be displayed. Air volume is calculated by entering the size and type of duct being measured and can be displayed in either cubic metres per hour or cubic feet per minute.
