The PSR+ The Ultimate Portable Spectroradiometer
The NEW PSR+ Series of spectroradiometers features a new standard for remote sensing applications in the field. Our sleek, compact design results in an full range NIR agricultural spectroradiometer that’s easier to handle and operate – there’s no better instrument for field work whether you are ground truthing satellite or flyover hyperspectral data, engaging in vegetation studies, performing canopy research, studying crop health and climate change, doing soil analysis – potential applications are virtually endless.
The PSR+ not only looks and feels great, we’ve also enhanced performance and reliability. System cooling has been enhanced with the new unibody anodized aluminum chassis with integral heat dispersion channels. Our new proprietary Sotex™ filter technology delivers improved order sorting for enhanced stray light performance and smoother transition between detectors.
