Pyranometer Solar Radiation Sensor, RS485/4-20mA

This pyranometer measures total solar irradiance across 280-3000 nm with a range of 0-2000 W/m², delivering stable and accurate performance. It uses a thermoelectric multi-junction thermopile with a high-absorption coating for high sensitivity and reliable data. The dual-layer glass dome provides up to 95% light transmittance, while the protective housing ensures durability in harsh outdoor environments. Built to WMO standards, pyranometer solar radiation sensor offers fast response, high accuracy, and long-term stability. It supports 0-20 mV, 4-20 mA, and RS485 outputs for easy integration with monitoring systems, making it suitable for meteorology, solar power, agriculture, and environmental applications.
