Accurate results – No matter the weather

All weather performance,
always confident

Increase confidence in site performance metrics by upgrading to the only pyranometer that prevents dew and frost using integrated dome heating. Designed for durability with the best-in-class surge protection, the IEC Class A compliant SMP12* pyranometer reduces unexpected maintenance costs and maximizes data uptime.

SMP12 Class A Pyranometer

With an outer dome that maintains a slightly higher temperature than the surrounding air, no morning dew and frost will interfere with the accuracy of your measurements. Now you can be fully IEC-61724:2021 compliant. Plus, solid-state heating technology enables less maintenance with no moving parts.

Integrated dome heating, zero moving parts

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.

Safeguard production with enhanced surge protection

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°.

The right tilt angle for reliable results

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 and IEC standards.

Durability to last + Class A compliance

Industry-standard RS-485 connectivity and the Modbus^® protocol make it easy to integrate with all your data loggers and SCADA systems. Plus, with dedicated pre- and post-sale support and services from OTT HydroMet, you have the technical expertise and turnaround times you need – right in your region.
