Anemometer Rotors
All of the A100 Series Anemometers manufactured by Vector Instruments utilise a highly sensitive yet robust 3-cup rotor from our R30 series. Manufactured from weather-resisting plastics, anodised aluminium and stainless steels, each rotor is individually calibrated in our own wind tunnel at one windspeed (9m/s) by comparison to one of a set of reference rotors which are themselves independently calibrated and traceable to national standards. Most other ...

Marine Anemometers
In environments where instruments are likely to be significantly exposed to sea/salt water (corrosive) or sand/dust (abrasive) it is advised that the 'marine' versions of our instruments be used in order that best performance and reliability is obtained in service. For applications requiring 'First Class' performance (wind assessment etc) the standard instruments will however produce better results than the /WR versions (as the /WR versions have not been ...
