Lufft ultrasonic anemometer and all in one weather station is designed with long life cycle in mind. We promise a long life cycle and effective return on investment with all our wind and weather sensors. Lufft offers many classes of sensors for a variety of applications. Class A sensors are available for precision testing. The robust VENTUS ultrasonic anemometer with a 240W heater is designed for use in extreme cold. Lufft climate monitoring equipment comes standard with heated sensors but is available unheated when a low powered sensor is needed. Mechanical and ultrasonic wind sensors accurately measure the wind reliably with rugged construction and maintenance free operation. Open communication protocols (including SDI-12) make the compact weather stations compatible with most dataloggers and systems.
