MS-40S Albedometer consists of two MS-40S pyranometers and a special albedo kit with a glare screen to measure albedo and total reflectance. It is used in solar power plants with bi-facial PV modules and in meteorological applications.

This Smart Albedometer has internal temperature, humidity and a 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 new Smart signal transducer which allows selecting from 4 types of output in one unit (MODBUS 485 RTU, SDI-12, 4-20mA, configurable 0-10mA / 0-1V with external optional 100Ω precision shunt resistor).  The new electronics ensure a ...
