Lightweight, reliable, compact, and easy-to-use, the PSR+ is designed for single-user operation in the field to collect critical remote sensing data. Spectral Evolution’s battery-operated portable NIR spectroradiometer can be outfitted with FOV lenses or fiber optics. Units can be handheld, tripod-mounted, or carried with a shoulder strap or backpack for easy use in the field. The PSR+ boasts best-in-class sensitivity at the highest resolution in any field handheld spectroradiometer. This spectroradiometer stores up to 1,000 spectra without a computer and can be used with a laptop or rugged tablet running DARWin™ LT on Windows 10.
