Yankee Environmental Systems, Inc. Multifilter Rotating Shadowband Radiometer MFR-7

The Multifilter Rotating Shadowband Radiometer (MFR-7) measures total, diffuse, and direct irradiance at six wavelengths (415, 500, 615, 673, 870, and 940 nm, each 10 nm FWHM) in the visible/NIR, and includes one unfiltered broad-band silicon pyranometer. Thermally stabilized, environmentally sealed state-of-the-art interference filters provide excellent long term calibration stability. Instead of using a rotating filter wheels the MFR-7 makes measurements simultaneously across all seven channels, meeting the Baseline Solar Radiation Network's requirements for atmospheric turbidity measurements. The shadowband enables the instrument to measure all three components of solar irradiance with one detector. The MFR-7 system includes the YESDAS-2 datalogger and works with YESDAS Manager data analysis software. The UVMFR, a shadowband instrument for the UV region, is also available.
