Ares Duo Sensor
The Ares Duo Sensor uses optical measurement via ultra-bright energy-efficient LEDs to provide indications of water quality via both turbidity and chlorophyll concentrations, and is ideal for environmental monitoring, oceanographic research, marine operations, and aquaculture. It offers both digital and analog outputs.
Each compact and low-power sensor is individually calibrated to laboratory standards, and is programmed with responses to red light produced via fluorescence by chlorophyll-a contained in algal cells, and to reflected light that can be converted to quantitative measurements of turbidity.
