Aquation Pty Ltd designs and manufactures a range of submersible and autonomous environmental monitoring equipment including chlorophyll fluorometers, field respirometry systems and water quality monitoring systems. Aquation also provides laboratory and land-based sensing and monitoring equipment. Our fluorescence products, designed for the assessment of plant health, range from a simple and inexpensive netbook-operated Classic Fluorometer to our state-of-the-art fully submersible Shutter Fluorometer with multiple shuttered sensors for automated dark acclimation. While originally developed for underwater applications, Aquation fluorometers are equally effective in terrestrial environments and provide an assessment of the photosynthetic efficiency of plants or algae for both commercial and research applications. Aquationâ€™s environmental assessment and water quality monitoring devices feature self-power, datalogging, telemetry and remote data-access functions.
