# Gill Instruments > Ultrasonic wind sensors, weather stations and optical rain gauges with no moving parts, designed and manufactured in the UK and used in over 150 countries. Gill Instruments has built ultrasonic anemometers since the 1980s, pioneering solid-state wind measurement to remove the mechanical failure points found in traditional cup and vane sensors. Products are designed and manufactured in Lymington, Hampshire, and serve national meteorological services, renewable energy operators, marine and defence organisations, and research institutions worldwide. Gill Instruments is part of Gill Group, which also includes Gill Sensors and Controls, Gill R&D and Labcal. ## Products - [All products](https://gillinstruments.com/products/): full range overview across weather stations, wind sensors, rain gauges and heat stress monitoring -
