SMP12 - Our most innovative pyranometer yet.

Expect clarity for all conditions, be it frost, dew, or snow. The new Kipp & Zonen SMP12 is a spectrally flat Class A pyranometer that delivers integrated heating with zero moving parts (solid-state technology) and best-in-class surge protection. Internal sensors to monitor the tilt angle and humidity help to minimize maintenance and verify instrument performance remotely.

Spectrally Flat, Fast Response

Spectrally Flat, Fast Response

Make accurate predictions of energy production and recognize system faults faster, for longer. The SMP12 has a leading mean time between failure (MTBF) of 10+ years. And it’s fully equipped and fully compliant with the latest ISO 9060:2018 and IEC 61724 standards.

Minimized Maintenance

Minimized Maintenance

Discover leading surge protection that helps you reduce failure risks, escape expensive on-site replacements, and maintain performance. Focus on plant performance and mitigate the impacts of poor grounding, finicky power sources, and lightning.

The right tilt angle for reliable results

Right Tilt Angle for Reliable Results

Improve the long-term reliability of your data knowing that the installation angle has remained constant. With the SMP12, you can remotely monitor tilt angle installation down to ±0.5°. Furthermore, an internal sensor monitors humidity to ensure proper operation.

Be Confident in Your Performance Ratio by Reducing Uncertainty with Kipp & Zonen Pyranometers

A pyranometer is an instrument that measures solar irradiance —specifically - the solar radiation flux density (in W/m²) that is the incoming solar power reaching the Earth’s surface.

Back in 1924, Kipp & Zonen became the first manufacturer of pyranometers. Today, OTT HydroMet proudly carries on the tradition of spectrally flat, incredibly accurate, and easy-to-maintain pyranometers.

Since 1924, Kipp & Zonen Has Led Pyranometer Performance Innovation
