The MS-093 is a high-quality sunshine duration meter. A unique measurement concept with rotating mirror and broadband sensor accurately measures the broad-band direct solar radiation.
The sensor utilizes a rotating mirror, which reflects the direct beam onto a pyro-electric detector once per revolution. By using this method, the MS-093 can measure the true direct broad-band radiation.
The MS-093 is unique compared to other dedicated sunshine duration sensors, which are based on an indirect measurement principle using photodiodes with a limited spectral range and accuracy.
