Industrial Class A and Class B albedometers

Hukx introduces "industrial-grade" albedometers. The alldigital Class A models SRA300-D1 and SRA200-D1, and Class B model SRA100-D1 albedometers are engineered to measure global and reflected solar radiation and solar albedo, also called solar reflectance, with the utmost reliability and measurement accuracy. Besides, Hukx offers other albedometer models with non-digital output signals and a lower - Class C - accuracy class. - complies with the latest ISO and WMO standards - the modular design facilitates maintenance and calibration Figure 1 Industrial albedometer model SRA300-D1. - the right...

Albedo and albedometers An albedometer is an instrument that measures both global and reflected solar radiation and, by calculation, the solar albedo, or solar reflectance for a particular ground surface. An albedometer is composed of two pyranometers, both installed horizontally, the downfacing one measuring reflected solar radiation. In the open field, the solar albedo depends on the directional distribution of incoming radiation and on surface properties at ground level. It is usually expressed as a single number, determined by taking an average over a day with solar elevation > 10 °. Changes...

Table 1 The building blocks of SRA300-D1, SRA200-D1 and SRA100-D1 albedometers are respectively the SR300-D1, SR200-D1 and SR100-D1 pyranometers. In the table below, the main specifications are compared. spectrally flat Class A spectrally flat Class A spectrally flat Class B IEC 61724-1:2021 compliance for solar irradiance measurement meets Class A PV monitoring system requirements meets Class A PV monitoring system requirements meets Class B PV monitoring system requirements for all locations and climatic conditions for locations where dew and frost are expected for < 2 % of annual GHI hours...

Most importantly, it is heated to mitigate dew and frost, and has an on-board tilt sensor. SR300-D1, SR200-D1 and SR100-D1 are tested and classified for Industrial Environments according to IEC 61326-1 and IEC 61000-6-2. When designing a measuring system, pyranometer users may reach...
