ALBEDOMETRE Classe B BLET Numérique Modbus RTU RS485

The BLET albedometer is made up of two identical class B pyranometers. The first, oriented upwards, measures the incident solar radiation, the second, oriented downwards, measures the reflected solar radiation. Albedo is the ratio of reflected light energy to incident light energy. It is therefore simply calculated by dividing the measurement result of the lower pyranometer by that of the upper pyranometer. This device can be used for example for meteorological and climatic observations or studies of reflectance of roofs.
