Precision measurement for demanding environments.
Forty years of ultrasonic anemometers, weather stations and optical rain gauges, designed and built in the UK. Our instruments are trusted by national meteorological services, defence programmes, wind energy operators and research teams in over 150 countries, delivering accurate data where reliability is critical.
Reliability, by design.
Ultrasonic measurement removes the failure points designed into traditional sensors. No moving parts means no wear, no drift and no degradation in challenging conditions. The result is stable, high-accuracy data with minimal maintenance, even in the most demanding environments.
Two flagship launches this year.
Both built on the same principle that has defined Gill for forty years: instruments that work without fuss, in places where failure is not an option.
TruMet PW100
Infrared optical rain gauge
Optical precipitation measurement with no funnel, no tipping bucket and no blocked drains. Accurate readings down to drizzle, designed for unattended weather networks and hard-to-reach sites.

Not sure which product fits?
Three quick decision routes. Pick the one that matches how you are scoping the project.
By environment
Marine, offshore, ATEX, icing, hazardous area, urban, defence range. Start with the conditions and the right product range narrows quickly.
View industries →By parameter
Wind only, full meteorological suite, precipitation, heat stress, 3-axis flux. Each parameter set maps to a different family of instrument.
Talk to a specialist →By integration
SDI-12, Modbus, NMEA, analogue, RS-232, RS-422 or proprietary protocols. Output format and platform compatibility usually drive the final shortlist.
Talk to engineering →Specifying for a particular deployment?
Three technical guides covering the applications engineers ask us about most. Full product range, integration notes, FAQs and the trade-offs that matter.
Awarded to Gill Instruments for International Trade.
Forty years of British engineering, 150+ countries served, and the King's Award for Enterprise for International Trade. Designed and built in the UK, trusted globally.
Read the story →Why engineers pick Gill.
Six reasons our customers give back to us, year after year, across forty years of measurement.
40+ years of ultrasonic
Gill pioneered the ultrasonic anemometer in the 1980s. Four decades of refinement sit inside every sensor we ship today.
Specified for headline projects
Mayflower Autonomous Ship, Saildrone world record, the Burj Khalifa, Plymouth Marine Laboratory. The list keeps growing.
No moving parts
Ultrasonic and capacitive technology eliminates the wear, bearing drift and icing failures of mechanical instruments.
Designed and built in the UK
Every product engineered and manufactured in the UK. Quality controlled end to end, with sovereign supply where it matters.
UKAS-accredited calibration
Through Labcal, the group's independent calibration laboratory, so the data you rely on is always verifiable.
Direct UK engineering support
Free configuration software, full documentation and direct access to UK-based engineers. No chatbot. No ticket queue.
Beyond the sensor.
Calibration & repair
UKAS-accredited calibration and factory repair through Labcal and the Gill service team. Keep instruments verifiable across their full operational life.
