The RSG2std Secondary Standard Class A Pyranometer is a premium-grade double thermopile solar radiation sensor designed for the highest level of accuracy in global solar irradiance measurements. Engineered to comply with ISO 9060 Secondary Standard (Class A) and WMO recommendations, it delivers exceptional precision for meteorological observations, photovoltaic performance analysis, and scientific research.
The advanced double thermopile sensing technology provides outstanding sensitivity, extremely low zero offset, excellent cosine response, and superior long-term stability. With an expected daily uncertainty of less than 2%, the RSG2std is ideally suited for high-accuracy solar resource assessment, climate monitoring, and calibration-grade applications.
Manufactured from anodized aluminium and stainless steel with IP67 protection, the sensor is built for continuous outdoor operation in demanding environments. It supports thermopile, analog voltage, current, and RS485 ModBus outputs, and is available with optional heating and ventilation units (VU) in accordance with IEC 61724-1 for enhanced performance in harsh weather conditions.
