Apogee SP-212

Pyranometer

Part # 51167

sp-212 pyranometer
sp-212 pyranometer

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.

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
