Wind Speed/ Direction Sensor is used for research, agro-meteorological and industrial applications. The Sensor can efficiently determine wind direction by using a varied choice of sensors and uses a range of operating principles that include mercury-wetted reed switch. The Sensor has accurate and precise methods for measuring average wind speed and can operate in low temperature like -30 degree C. Wind Speed/ Direction Sensor is made using quality grade raw material which ensures durability of use along with long lasting trouble free service.
