The MS-40 Albedometer consists of two MS-40 ISO 9060:2018 Class C Pranometers with the MS-Albedo Kit, plus glare screen. It is one of our most cost-effective irradiance sensors, designed to measure Solar irradiance across the full solar spectrum. It can be used for agro meteorological networks and professional small-scale PV sites where solar radiation is taken seriously.
MS-40 Pyranometers have a 5-year warranty and are manufactured with strict quality controls and performance evaluation. EKO provides calibration compliant with the international standards defined by ISO/IEC17025/9847 and a 2-year recommended recalibration interval.
