Davis Solar Radiation Sensor (SKU 6450) – Professional Pyranometer for Vantage Pro2

Capture the true power of the sun with the Davis Solar Radiation Sensor, designed to deliver reliable, decision‑ready solar irradiance data for agriculture, research, and energy management. Its engineered diffuser and housing provide excellent cosine response, while a high‑quality silicon photodiode ensures a clean match to the solar spectrum. Seamlessly add it to your Vantage Pro2 system to unlock evapotranspiration (ET) tracking, enhance your THSW index, and turn sunlight into smarter irrigation and operations. Choose it for robust outdoor durability, quick installation, and consistent performance day after day.

Key Benefits and Applications

• Smarter irrigation with ET — Feed accurate solar data into ET calculations to fine‑tune watering schedules, reduce water use, and protect yields.
• Climate and agronomy insight — Combine solar radiation with temperature, humidity, wind, and rain to understand crop stress, canopy conditions, and growth stages.
• Energy and PV optimisation — Correlate irradiance with photovoltaic performance, shade impacts, and site variability to validate output and plan maintenance.
• Research‑grade measurements — Depend on stable, repeatable readings supported by precise cosine response and factory calibration against secondary standards.
• Seamless Vantage Pro2 integration — Plug‑and‑play with your station and console to display instantaneous irradiance, cumulative solar energy, and the THSW index.

Featured technical specifications

• Measurement range — 0 to 1800 W/m², suitable for full‑sun conditions and overcast days.
• Resolution — 1 W/m² for fine‑grained trend tracking and modelling.
• Spectral response — 400 to 1100 nm to match the active solar spectrum captured by a silicon photodiode.
