The radiometric probes LP UVA 02, LP UVA 02AC, and LP UVB02AV measure the global irradiance in the UVA range on a flat surface (Watt/m²). The irradiance is the sum of direct solar irradiance and of diffuse irradiance from the sky. The radiometer can also be used for monitoring of indoor UVA irradiance.

The radiometer LP UVA 02 is based on a solid state sensor, the spectral match with the desired curve is obtained by using special filters. In order to protect the diffuser from dust, LP UVA 02 is equipped with a 50 mm glass dome. The cosine law response is obtained with a particularly shaped PTFE diffuser. The excellent cosine law response of LP UVA 02 allows to use the radiometer at any sun zenith angle. (The diffused component of the UVA increases as the sun moves away from the zenith, so the error on the direct component due to imperfect response according to the cosine becomes negligible on the measurement of global irradiance).
