MS-90 DNI Sensor
No Sun Tracker Required
A revolutionary design with proven reliability, the MS-90 is made to measure Direct Normal Irradiance (DNI) without a sun tracker based on a unique rotating mirror design that reflects the sunbeam onto a thermal detector.
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.
