Research grade normal incidence direct solar irradiance sensor (DNI), also known as pyrheliometer for short wave direct solar radiation. It complies with ‘First Class’ classification, from ISO9060 and WMO standards.
A unique product feature is the heated window, eliminating the formation of dew on the sensor window, making early morning measurements more accurate.
DPA259 is the first pyrheliometer to include a fast detector, making it ideal for high grade research or CPV applications..
Code: DPA259
