The Middleton Solar NSR1 Net Pyrradiometer measures the net total radiation flux (solar, terrestrial, and atmospheric) downward and upward through a horizontal surface. It is suitable for solar energy studies in agriculture and meteorology. The NSR1 is also available with separate downward and upward outputs, for no additional cost, see Dual output Application Note. The NSR1-E version has an inbuilt signal amplifier. An NSK4 Net Radiometer (with quad outout) is also available, as is the NSK2 Net Pyrgeometer (with dual outputs).
