EKO MS-80S Pyranometer

Capture highly accurate solar irradiance data with this fast-response and spectrally-flat class A sensor.

Details

The MS-80S Pyranometer is a unique pyranometer compliant to the "Fast response" and "Spectrally flat" sub-categories under ISO 9060:2018 Class A. Its innovative design consists of a small, single-dome / quartz diffuser construction that boasts remarkably low zero-offset behavior at an economical price. The MS-80S can be integrated with a heater and ventilator for use in regions impacted by dew, frost, snow, and dust.

The MS-80S is a digital sensor with Modbus RTU as well as analog output (4-20 mA and 0-1 V) options. The MS-80S includes onboard diagnostic measurements such as body temperature, pitch, and roll to help ensure optimal performance in a variety of environmental conditions.

The MS-80S is fully supported throughout NRG’s solar product offering including seamless integration with NRG's suite of data loggers as well as mounting support for SRA & SRM Systems and industry-standard PV array designs. Each MS-80S Pyranometer comes with an ISO 17025 certified calibration report including directional and temperature response characterization and validation.
