Multiparameter Sondes | Xylem Analytics

Offering the greatest value of any sonde available in the market, EXO3 combines the maneuverability of EXO1 with the powerful antifouling wiper of the EXO2. EXO3 is a purpose-built sonde for monitoring major water quality parameters, including: pH, conductivity, temperature, turbidity and dissolved oxygen.

Log real-time data, calibrate sensors, set-up sondes for deployment, and transfer water quality data to a PC with this feature-packed device. Designed for reliable field use in challenging environmental conditions, this display features a waterproof IP-67, impact-resistant case and wet-mate connector.

Instrument Only. Cables, probes/sensors, and accessories sold separately – please see the “Accessories” tab for details.

Capturing accurate data in fresh water, ground water and marine aquatic environments is easy with . The versatile multiparameter EXO1 sonde is ideal for estuarine, surface water, or ground water applications.

The EXO advanced water quality monitoring platform includes the versatile multiparameter EXO2 sonde for oceanographic, estuarine, or surface water applications. Collect data to 250m with the advanced EXO2 sonde – contains six replaceable ‘smart’ sensors and a central wiper to clean biofouling.

YSI EXO Wiped Conductivity & Temperature Sensor

YSI EXO Wiped CT Conductivity & Temperature Sensor

In long-term water quality monitoring, biofouling is public enemy number one. Biofilms, barnacles, and algal growth are common culprits of poor data quality, clogging up conductivity cells and coating sensor optics. While YSI EXO2’s Central Wiper can mechanically remove biofouling from other sensors to maintain data integrity over long deployment periods, the anatomy of a standard conductivity & temperature sensor makes this anti-fouling technique ineffective…until now.

Introducing the EXO Wiped Conductivity & Temperature sensor from YSI, designed with and engineered for compatibility with EXO2’s Central Wiper.

EXO2 Central Wiper

YSI EXO2 Central Wiper

Monitor without interruption and reduce biofouling

The EXO2 Central Wiper occupies the central port on an EXO2 sonde, and is used to keep the payload sensor faces clean during long-term deployments. There’s no escaping biofouling in underwater measurements. To keep it from interfering with data, an EXO2 sonde can be equipped with this anti-fouling wiper to prolong deployments and improve data accuracy.
