Pyranometer for Weather Instruments

A pyranometer is a precision instrument designed to measure global solar irradiance received from the entire hemisphere above the plane of installation. This includes both direct solar radiation and diffuse sky radiation. Utilizing a high-quality silicon photodiode sensor, the pyranometer provides accurate and stable readings over a broad spectral range of 400 to 1100 nm.

Engineered for reliable field performance, it can operate in extreme environmental conditions ranging from -40°C to +65°C. Its cosine-corrected design ensures accurate measurement regardless of the sun’s position or angle of incidence. The device is widely used in meteorological, agricultural, and solar energy applications to monitor solar energy levels and optimize system performance.
