【English Introduction】
The SR20-D1 Pyranometer, developed by Hukseflux, is a high-precision solar radiation measurement instrument designed for meteorological observation, environmental monitoring, solar energy resource assessment, and agricultural research. Utilizing thermopile detection technology, this device provides comprehensive radiation data by measuring broadband solar irradiance (280-3000 nm) with full spectral response, capturing both direct, diffuse, and reflected radiation components.
Featuring a dual-layer quartz glass dome, the SR20-D1 ensures high light transmittance while minimizing environmental interference. The specially treated hydrophobic coating on the dome surface effectively reduces contamination accumulation, maintaining measurement stability during prolonged outdoor deployment. An integrated temperature compensation mechanism enables consistent accuracy across a wide operational range from -40℃ to +80℃, supporting continuous monitoring under diverse climatic conditions.
Constructed with corrosion-resistant aluminum alloy and IP67-rated enclosure, the sensor demonstrates exceptional resistance to moisture and salt spray, making it suitable for coastal, desert, and high-altitude environments. Its modular design facilitates quick installation and maintenance, while the built-in leveling base simplifies angle calibration. The device offers flexible connectivity through analog voltage outputs (0-1 V / 0-5 V) and digital RS-485 interface, ensuring compatibility with various data acquisition systems.
Laboratory-grade optical calibration ensures measurement alignment with global radiation reference standards. The self-cleaning design minimizes maintenance requirements, and the accompanying software suite provides real-time data visualization and historical analysis capabilities. These features make the SR20-D1 a reliable solution for both scientific research and industrial applications requiring accurate solar radiation data.
