Davis Anemometer — Professional wind sensing for precise, real‑world decisions

The Davis anemometer delivers trusted, professional wind measurements with exceptional reliability. Choose the classic cup‑and‑vane design or a maintenance‑free ultrasonic option to track real wind behaviour with fast response and stable readings. Built to thrive in harsh environments, it integrates seamlessly with Davis weather systems and supports confident decisions in agriculture, energy, construction, marine and research. Partner with Stratosens.com to equip your site with a robust, field‑proven wind sensor that is easy to install and built to last.

Key Benefits and Applications

• Reliable data in any weather — Engineered for consistent performance in strong gusts and gentle breezes, providing dependable speed and direction information for year‑round operations.
• Two sensing technologies to fit your project — Select the rugged cup‑and‑vane for proven mechanical durability or the ultrasonic version with no moving parts for minimal maintenance and quiet operation.
• Seamless system integration — Works with Davis Vantage Pro2 and can be used as a dedicated wind station or within EnviroMonitor networks, ideal for farms, smart buildings and industrial sites.
• Fast, actionable wind insights — High‑resolution direction and responsive speed updates help optimise irrigation, crane or drone operations, turbine cut‑in and site safety protocols.
• Installation made simple — Supplied with mounting hardware and a long cable run for flexible siting on masts, rooftops or poles so you achieve optimal exposure with minimal effort.
• Low lifetime cost — UV‑stable materials, sealed bearings on the mechanical model and a solid‑state ultrasonic option reduce maintenance and extend service life.

Featured technical specifications

• Measurement range and accuracy — Cup‑and‑vane (Model 6410): wind speed from 0.5 to 89 m/s with accuracy ±1 m/s or ±5 percent, whichever is greater. Sonic (Model 6415): wind speed from 0 to 40 m/s with accuracy ±1 m/s or ±4 percent, whichever is greater.
• Wind direction performance — Numeric display resolution of 1°. Cup‑and‑vane accuracy ±3°. Sonic accuracy ±2° at speeds ≥ 3 m/s and ±4° below 3 m/s.
• Operating temperature — Cup‑and‑vane: −40 to +65 °C. Sonic: −15 to +55 °C.
• Power — Cup‑and‑vane: passive sensors powered by the connected Davis station. Sonic: integrated solar power with battery backup for autonomous operation.
• Cabling and connectors — Supplied with a 12 m attached cable. Modular RJ‑11 connector with 4‑conductor, 26 AWG cable. Maximum cable length up to 73 m for the cup‑and‑vane model and up to 76 m for the sonic model, noting that extreme extensions reduce the maximum displayable wind speed.
• Materials and build — Cup‑and‑vane: UV‑resistant ABS wind vane, polycarbonate cups and black‑anodised aluminium arm with sealed bearings for long life. Sonic: polyacetal control head on a clear‑anodised aluminium arm with no moving parts.
• Proven robustness — Cup‑and‑vane assembly wind‑tunnel tested to withstand 322 km/h, providing confidence in storm conditions. Sonic design minimises wear by eliminating mechanical components.
• Compatibility and system options — Integrates with Vantage Pro2. Can be used as an additional wind station with a Sensor Transmitter and WeatherLink Live or connected to an EnviroMonitor Node. The sonic model may require an RJ connector node adapter in specific EnviroMonitor configurations.
• What is included — Both versions include mounting hardware and a 12 m cable. The sonic model also includes a battery and an aligning tool to simplify orientation during installation.
