Portable AI-based imaging system for rapid physical analysis



To understand how microplastics break down, move through the oceans and freshwater systems and collect on coastlines, researchers and community monitoring groups must quantify a robust set of particle size parameters. 

Saturna is a portable, standardized imaging and illumination device that plugs in to your computer and syncs with Mariana, our web-based data analysis portal, to rapidly characterize and quantify visible microplastic particles. 

Use it to collect a robust set of size, color and categorical metrics for visible microplastic samples (>400μm) like those collected from Manta trawls, neuston nets, beach quadrat samples and community studies.
