The SPN1 Sunshine Pyranometer provides a simple, reliable solution for measuring global and diffuse solar irradiance in meteorological and environmental monitoring applications. Using Delta-T Devices' proven thermopile technology, it delivers accurate irradiance measurements across a wide range of atmospheric conditions while requiring minimal maintenance.

Unlike conventional diffuse measurement systems that rely on rotating shadow bands or tracking mechanisms, the SPN1 has no moving parts and requires no routine adjustment or alignment. This significantly reduces maintenance requirements while improving long-term reliability, making it particularly well suited to remote monitoring stations and long-term environmental research programmes.

The SPN1 simultaneously measures global and diffuse solar irradiance, enabling Direct Normal Irradiance (DNI) to be calculated without the complexity of traditional instrument combinations. Its spectrally flat thermopile sensors provide stable, research-quality measurements across the full solar spectrum, ensuring excellent performance under clear, cloudy and variable sky conditions.

Widely used in meteorological networks, climate research, hydrology, agriculture and ecosystem monitoring, the SPN1 provides dependable, high-quality solar radiation data for a broad range of environmental applications. Combining robust construction with low operating costs, the SPN1 offers researchers an efficient and cost-effective alternative to traditional shadow-band pyranometers and pyrheliometer-based measurement systems.
