ECO-PAR - Aquatic PAR Sensor

Satlantic and WET Labs have partnered to develop the ECO-PAR sensor, which provides highly accurate measurements of PAR (400–700 nm) in all aquatic environments.

Equipped with quality precision optics and proven Bio-wiper technology, the ECO-PAR sensor can be deployed for extended periods without a reduction in data quality caused by biofouling. Additionally, the ECO-PAR has optional internal data logging and power capabilities, precluding the need for an external logging device and battery pack.

Research applications

• Long-term monitoring on moorings and buoys
• Water quality studies
• Phytoplankton physiology and photosynthesis studies
• Aquatic productivity studies
