These weather instruments, initially designed at the Chemical Defence Establishment at Porton Down in the UK during the 1960s, have been manufactured and improved by Vector Instruments since 1972 with a range of instruments for different purposes being available today.
All of our anemometers and windvanes are based on these original tried and tested Porton™ designs.
Updated versions of the original Porton™ anemometer and windvane, with improved performance, continue to be manufactured today.
