Description

The MS-80 Albedometer combines two MS-80 pyranometers with the MS-Albedo Kit and a glare screen. It is designed to measure albedo with the lowest possible uncertainty across demanding applications, including meteorology and solar power plants with bifacial PV modules.

It delivers ultra-fast, spectrally flat response with exceptionally low zero offset, analog output, a 5-year warranty, and a recommended 5-year recalibration interval. The MS-80 is an ISO 9060:2018 Class A benchmark and an IEC 61724-1 compliant option for photovoltaic performance monitoring and large weather sensor networks.

The patented design uses an isolated thermopile detector, hermetically sealed beneath a pure quartz diffusor in a compact single-dome housing. The diffusor passes all solar wavelengths while reducing the total energy received at detector level, including harmful UV irradiance, improving accuracy, speed, and reliability.

MS-80 sensors are manufactured under strict quality controls. EKO provides calibration compliant with ISO/IEC 17025/9847, validated by a measurement report supplied with the sensor.
