The ES-S228AT thermoelectric total radiation sensor is a shortwave total radiation sensor used for solar radiation observation. It is a Class C total radiation sensor conforming to the latest ISO 9060 and WMO technical standards.

The ES-S228AT thermoelectric solar total radiation sensor measures the irradiance received on the Earth’s plane, primarily used to measure total solar radiation in the spectral range of 0.285-3 μm. When placed horizontally downwards, it can measure reflected radiation; with a diffraction-shielding ring, it can measure scattered radiation.
