Given its high resolution, ease of use, and clean data (we collected data with a lens and not a contact probe), the PSR+ was incredibly useful in the field for snow/ice applications.

With a range of 280nm-1900nm the Spectral Evolution SR-1901 is an extremely versatile, lightweight and simple instrument for many microbiological applications.

Dr. Kurt Hanselmann, ETH Zurich, Microbiologist

Very satisfied with the instrument  (PSR-1100f) and it’s very stable compared to other field spectroradiometers.
