Sonda Multiparamétrica YSI EXO2 ²⁶

EXO2 Multiparameter Sonde for Advanced Water Quality Monitoring

The most versatile platform on the market with multiple depth and sensor configurations to adapt to any environmental challenge.

The EXO2 multiparameter sonde is an extremely robust and adaptable water quality monitoring solution, designed to deliver data of unmatched precision in long-term deployments. This platform stands out for its technical flexibility, offering various versions including options without a depth sensor or with integrated sensors for ranges of 10, 100, and 250 meters. Its architecture allows for the integration of up to seven smart sensors, making it the ultimate tool for researchers looking to document the health of rivers, estuaries, and oceans with total reliability and minimal intervention.

Key Features

• Available in multiple depth variants to optimize precision based on the study environment.
• High-durability titanium architecture rigorously tested in extreme ecosystems.
• Seven universal ports allowing for rapid sensor exchange without the need for external recalibration.
• High-power central anti-fouling wiper that ensures data purity for months.
• "Wet-mate" neoprene connectors and impact-resistant housing for total underwater protection.
• Autonomous operational capacity exceeding 90 days thanks to its smart power management.
