MS-80S Albedometer consists of two MS-80S smart pyranometers and a special albedo kit to measure the albedo with the lowest uncertainty.

This Smart Albedometer has internal temperature, humidity and tilt sensors for remote diagnostics. These additional internal sensors will help the user to monitor the stability of the irradiance sensors as well as to ensure its proper installation and maintenance practices.

The albedometer can be equipped with optional ventilation and heater units MV-01.

MS-80S Albedometer is the ideal instrument for solar power plants with bi-facial PV modules, outdoor material testing and in various meteorological applications.

MS-80S pyranometers have a 5 year warranty, 5 year recommended re-calibration interval and no longer the requirement for the desiccant to be changed.
