A revolutionary design with proven reliability, the internal rotating mirror of the MS-90 DNI Sensor is based on the hugely successful MS-093 sunshine duration meter, deployed across Japan for over 10 years at over 800 AMeDaS network weather stations. Designed to accurately measure Direct Normal Irradiance (DNI) without a sun-tracker, the MS-90 is ideal for solar energy monitoring systems and meteorological networks.

Based on a revolutionary design, the MS-80SH Pyranometer is best-in-class for accuracy, speed, reliability and is one of the only top tier 'fast-response' and 'spectrally flat' Class A pyranometers with unprecedented low zero-offset behaviour available.

Featuring a state-of-the-art thermopile detector and Quartz diffusor technology, new internal diagnostics, a unique 4-channel interface, and Level A EMI/EMC electronic surge filter protection, the MS-80SH is IEC 61724-1 compliant and the standout choice for every application.

Sealed inside an IP65 all-weather case, with GPS receiver, and Modbus 485 RTU output, the C-Box Modbus processing interface enables a range of sensor control and data processing functions.

Working in tandem with the ISO 9060:2018 Class A leading MS-80SH pyranometer, the C-Box, is an essential component of the unique MS-80SH Plus+ trackerless solar monitoring solution, allowing the system to accurately measure DNI, GHI, and to calculate DHI from measurement data and the position of the sun.
