MS-60 Albedometer


Make: Eko (Japan)

Model: MS-60 Albedometer

  • ISO 9060:2018 Class B (First class)
  • Sub-category “Spectrally flat”
  • Analog output
  • ISO 17025 certified calibration
  • Optional ventilator MV-01
  • 5 year warranty

MS-60 Albedometer consists of two MS-60 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.

The MS-60 is an ISO 9060:2018 Class B (First class) pyranometer with analog output and improved performance. The new double dome constructions provides lower offsets and cosine errors.

The MS-60 pyranometers are manufactured in a consistent way followed by strict quality inspection and performance evaluation. EKO provides a unique calibration compliant to the international standards defined by ISO/IEC17025/9847. The sensor has a 5-year warranty with a 2 years re-calibration interval recommended and it is no longer necessary to change the desiccant
