Industrial series Class A and Class B albedometers
Hukx introduces “industrial-grade” albedometers. The all-digital 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.
- the right albedometer for every application and budget
- main applications: PV system performance monitoring and meteorology
- integrated surge protection, designed to withstand the extreme conditions encountered on PV power plants and meteorological stations, upgradable to 4 kV with optional SPD01 Surge Protection Device
- complies with the latest ISO and WMO standards
- the modular design facilitates maintenance and calibration

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 of albedo are typically slow and seasonal, except when it snows.
Albedos of typical surfaces range from about 4 % for fresh asphalt and 15 % for green grass to 90 % for fresh snow.
SRA200-D1 design
To create an albedometer, two sensors are combined with one AMF03 albedometer mounting kit. AMF03 includes a fixture with a rod for mounting purposes and a glare screen. The user assembles these modular components into an albedometer. The modular design facilitates maintenance and calibration.
Using the albedometer is easy. The instrument is composed of two pyranometers. The irradiance in W/m2 is transmitted via the Modbus protocol over 2-wire RS-485. The working principle and specifications of the pyranometers can be found in the pyranometer user manuals. The pyranometers can be connected directly to commonly used data logging and SCADA systems.
Industrial-grade, high-accuracy and reliable
SRA200-D1 consists of two identical pyranometer models SR200-D1, one facing up, one facing down. SR200-D1 complies with industrial-grade immunity, emission, electrical, environmental, and safety requirements for use in these outdoor industrial environments, significantly improving measurement reliability. Ease of operation is further enhanced through advanced functionality and diagnostics.
Surge protection in industrial environments: immunity to high-impulse voltages & currents
SR200-D1 is 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 several levels of immunity. With the optional Surge Protection Device SPD01, this immunity can be increased to 4 kV.
Optional accessories
We offer accessories for use with the SRA200-D1 including electrical and mounting hardware options.
- SPD01 Surge Protection Device to upgrade Surge Protection to level 4 (for up to 3 pyranometers) for cables longer than 3 meters
- ALF01 albedometer leveling fixture
- CMF01 crossarm mounting fixture
ALF01
ALF01 is a leveling tool that can be used with AMF03 to easily level the instrument. The ALF01 is mounted on a 1 inch outer diameter crossarm, and can be rotated around the tube axis for 360 ° as well as tilted over ± 2 °.
