MS-40S

The S-Series MS-40S ISO 9060:2018 Class C pyranometer is a cost-efficient part of the most accurate, reliable and robust family of pyranometers in the world and the class-leading solution for system integrators, agrometeorological networks, and professional small-scale PV sites.

Built with the same unique S-Series features as the Class A MS-80S and Class B MS-60S, the MS-40S comes with internal diagnostic sensors for remote visibility over internal temperature, humidity, tilt and roll angle, ensuring optimum performance with reduced maintenance costs.

EKO’s 4-channel smart interface ensures that the MS-40S is compatible with 99% of data loggers, DAQ, and SCADA systems and with Level A EMI/EMC electronic surge filter and protection, 5-year warranty, lifetime desiccant, and ISO 17025 accredited calibration, the MS-40S is the toughest, most reliable, and advanced Class C pyranometer available.

The MS-40S Albedometer consists of two MS-40S Pyranometers and the MS-Albedo Kit with a glare screen to measure albedo and total reflectance across various applications, including solar power plants with bi-facial PV modules.

MS-40S Pyranometers are manufactured with strict quality controls and performance evaluation. EKO provides calibration compliant with the international standards defined by ISO/IEC17025/9847 with a 2-year recommended re-calibration interval.

 

Key Features:

 

  • 5-year warranty & recommended 2-year recalibration interval
  • Smart 4-channel Analogue & Digital Interface
  • Level A EMI/EMC electronics surge filter & protection
  • Internal Diagnostics for temperature, tilt, roll, and relative humidity

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor sit amet..”, comes from a line in section 1.10.32.

The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from “de Finibus Bonorum et Malorum” by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.
