- YSI has used its long experience in water-quality monitoring to develop the ultimate multiparameter sondes for challenging marine and freshwater conditions.
- Users can choose the new EXO1 sonde, with ports for four sensors, or the new EXO2 sonde, with six ports and a central anti-fouling wiper.
- Parameters include: temperature, conductivity, depth, dissolved oxygen, pH, ORP, total algae (blue-green algae and chlorophyll), turbidity, and fDOM, plus four calculated parameters.
- Key Benefits
- -CTD plus 3-5 additional sensors in one small package;
- -High-accuracy sensors with on-board memory;
- -Wireless communications; and
- -Seamless integration into marine, estuarine, freshwater and ground water monitoring systems.
- Smart Sondes and Sensors
- “EXO was designed to be extremely versatile, allowing the user to configure a sonde for different applications in minutes. The key to this versatility is the smart sensors and smart ports,” explains Rob Ellison, YSI director of R&D. “Each smart port is identical and automatically recognizes any EXO sensor so sensor payloads are designed by the user.”
- Monitor without Interruption
- -No matter which EXO sensors users select, other features of the sensors’ design make them rugged and durable:
- -Wet-mateable connectors resist corrosion.
- -Isolated components prevent short circuits.
- -Welded housings and double o-rings prevent leaks.
- -High-impact plastic and titanium resists breaking.
- -Built-in antifouling systems protect data integrity.
- -Low power consumption extends underwater deployments.
For long-term monitoring programs, the data collected by EXO sensors are compatible with historic data from YSI 6-Series sensors, helping users to maintain a consistent record of measurements.
- Accuracy
- EXO sensors and sondes are tested in a variety of rigorous field conditions as well as lab conditions to ensure accuracy and response times.
- “With YSI's focus on building monitoring systems for natural environments, our sensor specifications are based on the entire range of environmental extremes that a system could encounter in nature. Sensors have fast response times for profiling and sampling and a depth rating of 250 meters,” notes EXO Product Manager Tim Finegan.
- Also, a new metrology system specifically for EXO offers improved accuracy of conductivity and temperature sensors to better address oceanographic challenges.
- Applications
- -Long-term continuous monitoring;
- -Vertical profiling;
- -Underway monitoring;
- -Integration into remote monitoring platforms;
- -Source Water monitoring;
- -Ground Water monitoring;
- -Stormwater monitoring;
- -Dredging;
- -Spot sampling; and
- -Stand-alone sensors.
- Accessories
- -Enhanced KOR interface software;
- -Handheld display; and
- -Multiple data output options, including DCP, USB, and Bluetooth wireless communication.
