The Apogee SP-212 is an accurate, reliable, and durable pyranometer featuring a silicon-cell photodiode with excellent cosine response and measures total solar radiation to within ±5%. The SP-212 is fully potted with a domed-shaped head making the sensor fully weatherproof, self- cleaning, and impervious to thermal based accuracy fluctuations. Each SP-212 pyranometer is carefully pre-calibrated in controlled conditions and traceable to ISO class reference standards so the sensor is ready to go right out of the box.
- 4-year warranty
- Comes with Apogee level plate (AL-100) and mounting bracket (AM-110) for easy setup and installation.
