Algae Online Monitor(AOM)

Soil & CropsPhotosysnthesis Chlorophyll & Respiration

Algae Online Monitor (AOM) is a portable, robust device for online detection and continuous monitoring of photosynthetic microorganisms in both natural and artificial water bodies. It can serve for detection and discrimination among variety of cyanobacteria, green and brown algae, diatoms, and other microbes. Its ultra-high sensitivity (30 ng Chl/l) allows early detection of very low concentrations of these organisms.
