The WAA252 is a fast-response, low-threshold anemometer. Three lightweight, conical cups mounted on the cup wheel, provide excellent linearity over the entire operating range, up to 75 m/s.
This anemometer is mostly used in cold climates given its foil heaters integrated into the cups. Heating power is also supplied to the sensor shafts, bearings, and bodies. This keeps the sensor bodies free of ice, which is important for maintaining the aerodynamic performance.
The anemometer is supplied with a MEASNET calibration certificate, and it is fully compatible with our data loggers.
