The STR-21G-S2 is designed to perform the most accurate solar radiation measurements of the three solar radiation components; Direct, Diffuse and Global. Easily integrated into any DAQ system with multiple analog or digital inputs, the STR-21G-S2 features an in-built sun-position sensor and GPS receiver for quick and easy set-up.

Based on the STR-21G Sun tracker with a new shading disk assembly which can be mounted on one arm of the tracker, the system also features the industry-leading Class A MS-80S pyranometer and Class A MS-57 Pyrheliometer. Altogether, the STR-21G-S2 is the most “high-end” sensor system for solar energy research.

The STR-21G-S2 can also be freely configured to measure the required solar radiation components in the most accurate way, ensuring a cost-effective solution for every application.

In harsh environments, the MS-80S can be paired with the optional MV-01 ventilator & heater, while the MS-57 Pyrheliometer features a heated front window, protecting both sensors from condensation and ice for continuous accuracy, whatever the weather.
