Description
Accurate measurements for IEC61724-1 compliance
The diffusometer is a precision instrument specifically designed to measure diffuse solar radiation. Unlike traditional systems that rely on external shading accessories, the SRD100 features an innovative internal shading mechanism that blocks direct sunlight, enabling accurate measurements even under the most demanding conditions. The instrument complies with IEC61724-1 requirements for class A photovoltaic (PV) monitoring systems.
Compact and robust design with minimal maintenance
The SRD100 features a compact and robust design and includes an internal heater to prevent dew and frost formation on the glass dome. Thanks to its compatibility with conventional data acquisition systems, the instrument can be easily integrated into meteorological stations and solar monitoring systems, providing reliable data with minimal maintenance.
