PYR20 Pyranometer, or Solar Radiation Sensor, measures global solar irradiance, including both direct and diffuse radiation. Internal temperature compensation minimizes measurement errors caused by sensor heating. Each unit is calibrated against an Eppley Precision Spectral Pyranometer, ensuring high accuracy and consistency. Suitable for scientific research, solar power monitoring, greenhouse applications, and weather stations. Measurement range: 0–2000 W/m² Spectral range: 400–1100 nm Output options: RS485, voltage, or current (4–20 mA) Temperature compensated Equipped with level indicator and spring-loaded mounting mechanism Ingress protection rating: IP66 High accuracy and long-term stability Reverse polarity protection and built-in TVS/ESD protection Directional error: 3% (0°–70°), 10% (70°–85°) Operating temperature range: –40°C to +85°C Mounting: Three screw holes Color: Black Material: Plastic Package includes: 1 × Sensor Note: Color appearance may vary slightly due to lighting conditions and display settings. Measurement tolerance: ±1–3 cm.
