The STR-21G-S is EKO's new integrated measurement system to measure all Solar irradiance components (DNI / GHI / GDI). The system is based on nowadays most advanced sensor and sun tracker technology, which provide the lowest measurement uncertainty in accordance with ISO 9060.
The STR sun tracker is an established reference and was deployed to many research projects in the world including Antarctica. With the cutting edge MS-80 Secondary standard pyranometer and MS-56 First Class pyrheliometer the STR-21G-S system can be freely configured to measure the required Solar radiation components. Hence a cost effective solution can be created for each application.
As an option the MV-01 ventilator & heater can be used with the pyranometer to ensure data availability. The MS-56 pyrheliometer has a standard heated front window to avoid condensation, snow and ice.
