The STR-21G-S0 is (MTI.AWS.EK.21GS0) a turnkey sensor system designed to perform the most accurate solar radiation measurements of direct solar radiation. Compatible with almost all DAQ systems, with multiple analog and digital inputs, the STR-21G-S0 is equipped with an internal sun-position sensor and GPS receiver for quick and easy set-up.
Based on the STR-21G Sun Tracker, in combination with the Class A MS-57 Pyrheliometer, the STR-21G-S0 system can be freely configured to measure the required solar radiation components in the most accurate way. The MS-57 has a heated front window to avoid condensation and ice, which can affect the measurements, ensuring uninterrupted accuracy, whatever the weather
