Descrição Técnica

The CS305-ETM measures total sun and sky solar radiation using a silicon photocell. The spectral range is 300 to 1000 nanometers, which encompasses most of the shortwave radiation that reaches the Earth's surface.

The standard output is 0.005 mV per W m-2, which provides a signal of 5 mV in full sunlight (1000 W m-2). All our data loggers, except the CR200(X) series, can measure this output. Therefore both the ET107 and ET106 are compatible.

Compatibilidade

The connector attaches to an ET107 or ET106 Weather Station.
