EKO MS-40 Pyranometer:

The MS-40 pyranometer is a cost-effective and reliable solution for measuring solar irradiance across the entire spectrum. As an ISO 9060:2018 Class C pyranometer, it is based on EKO’s universal sensor platform and is specifically designed for agro-meteorological networks and professional small-scale PV sites. The MS-40 offers high accuracy and reliability and is a great option for anyone in need of solar irradiance measurements.

One of the key features of the MS-40 is its analog (mV) output, which makes it compatible with the optional MV-01 ventilator & heater and albedo mounting kit. This allows for even more versatility and functionality, making it an excellent choice for various applications. Additionally, it is manufactured with strict quality controls and performance standards, ensuring that it meets the highest standards of accuracy and durability.

EKO provides a unique calibration that complies with the international standards defined by ISO 17025 and ISO 9847. This ensures that the MS-40 is able to deliver accurate and reliable measurements, even in challenging environments. With this unique calibration, you can trust that the MS-40 will provide you with consistent and precise measurements.

In addition to its outstanding performance, the MS-40 also comes with a 5-year warranty, which is a testament to its durability and longevity. Furthermore, it has a two-year recommended recalibration interval, which ensures that the device stays accurate and reliable over time. Moreover, the MS-40 does not require the changing of desiccant, which makes it easy to maintain and use.

Overall, the MS-40 is a cost-effective, reliable, and easy to maintain option for measuring solar irradiance. Its analog (mV) output, compatibility with the optional MV-01 ventilator & heater and albedo mounting kit, unique calibration compliant with international standards, 5-year warranty, two-year recommended recalibration interval, and no requirement to change the desiccant make it an excellent choice for anyone in need of accurate solar irradiance measurements.
