Additional Information

Features & Benefits

Precision pyranometer

Detects solar radiation  at wavelengths of 300 to 1100 nanometers. Solar radiation data is required (along with an anemometer and a temperature/humidity sensor) enables the weather station to report ET and THSW Index.


Designed for accuracy

  • Diffuser element and housing are carefully designed for accurate cosine response.
  • Silicon photo diode provides good match to solar spectrum.

Stands up to the weather

  • Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust.


  • Solar radiation sensor with built-in level
  • 2 ft (0.6 m) cable


  • A  Vantage Pro2 sensor suite. Note: Vantage Pro2 Plus and GroWeather already include this product.
  • A Sensor Mounting Shelf (#6673) for mounting to a Vantage Pro2 sensor suite.
