Amour - Advanced Multi-purpOse Usb RadiometerAmour - Advanced Multi-purpOse Usb RadiometerThe newly developed Advanced Multi-purpOse Usb Radiometer (AMOUR) is a high-speed USB Radiometer for research and engineering in the laboratory or field. The instrument is very versatile as the user can select different front-optics (e.g., for measuring irradiance, scalar irradiance, radiance) and different spectral responses (e.g., narrow band, wide band, PAR). The instrument is relatively inexpensive, small, and convenient as it directly connects to your PC.  The dynamic range of the instrument covers more than 10 orders of magnitude. It incorporates Biospherical Instruments' microradiometer technology, which was developed under a contract to NASA.
