EKO MS-80 Pyranometer:

The MS-80 is a top-of-the-line pyranometer that is perfect for scientific research, industrial applications, and photovoltaic system performance monitoring. With its fast-response and spectrally flat design, it offers unprecedented low zero offset, analog output, and a 5-year recalibration interval. The MS-80 is an ISO 9060:2018 Class A leader and the IEC 61724-1 compliant go-to option for large weather monitoring sensor networks around the world.

One of the key features of the MS-80 is its patented design, which includes an isolated thermopile detector. The detector is hermetically sealed under a pure Quartz diffusor and housed within a compact single-dome. This design allows all solar wavelengths through while ensuring that the total energy received at the detector level, including harmful UV irradiance, is substantially lower than usual. This feature ensures that the instrument is able to measure accurately even under extreme weather conditions such as high temperature, humidity, or UV radiation.

The MS-80 is also built with durability and longevity in mind, it is designed to withstand harsh environmental conditions, it is weatherproof and corrosion-resistant. The MS-80 is built to last and that is why it comes with a 5-year recalibration interval, which is much longer than most other pyranometer in the market. This means, you can rely on the MS-80 to provide accurate measurements for a longer period of time without needing frequent recalibration.

Furthermore, the MS-80 is equipped with an Analog output, this feature allows you to easily integrate the MS-80 into your existing systems and data loggers. This feature allows for easy integration into SCADA systems and allows for real-time monitoring and data collection. The MS-80 is a versatile instrument that can be used in a wide range of applications, it is suitable for both indoor and outdoor use. It is a reliable and accurate instrument that is built to last and that is why it is a go-to option for scientific research, industrial applications, and photovoltaic system performance monitoring. With its advanced features and unique design, the MS-80 is the ideal choice for those who demand the best in performance and reliability. Whether you’re conducting scientific research or monitoring photovoltaic system performance, the MS-80 is the perfect instrument for your needs.
