We've combined our field proven know-how with the latest innovations to the YSI water quality monitoring sonde range. They are ideal for long-term in situ monitoring and profiling projects. Features can include real-time turbidity monitoring, optical dissolved oxygen monitoring, algae monitoring, bluetooth comms and more.
Capturing accurate data in fresh water, ground water and marine aquatic environments is easy with the versatile multiparameter EXO1 sonde. 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.
Go more places with YSI EXO2s (Shorty) sonde! The more maneuverable monitoring platform.
This is the EXO2s conversion service only.
EXO2 sonde, cables, probes/sensors, and accessories sold separately.
We have heard from customers who need the payload and capabilities of YSI's best-in-class EXO2 sonde, but in spaces and places that can't accommodate the EXO2. EXO2s is a customized, batteryless sonde that comes with the same warranty and capabilities as the EXO2
EXO3 is a purpose-built sonde for monitoring major water quality parameters, including: pH, conductivity, temperature, turbidity, and dissolved oxygen. Offering the greatest value of any sonde available on the market, EXO3 combines the maneuverability of the EXO1 with the powerful antifouling wiper of the EXO2.
The portability of EXO GO wireless communication frees up your hands in the field. EXO GO opens a Bluetooth® portal between any Windows OS device and a submerged EXO Sonde. (EXO 1, EXO 2, EXO 2s Shorty, EXO 3)
This adapter converts an EXO sonde signal into either SDI-12 or RS-232.

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.
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.

YSI offers several PAR systems that can be directly integrated into existing or new 6600 multiparameter sondes. PAR sensors are powered by the sonde and PAR data is added to the data stream of the water quality sonde.
Anti-fouling nanopolymer coating that inhibits biofouling attachment on conductivity-temperature probes and other sensors and water quality instruments. 100 mL bottle.
Copper tape for water quality sondes and sensors provides biofouling protection and extends deployments.
This copper-alloy sonde guard for the EXO1 protects water quality sensors and provide bio-fouling protection.
The copper construction naturally resists fouling agents in the water and prevents organisms from attaching to the guard.
These protective probe and sonde sleeves incase your equipment in an extra layer of protection. Fouling that attaches to this sleeve can be easily removed by simply cutting off and disposing of the sleeve.
Introducing the updated EXO Handheld from YSI - In water quality monitoring, instruments must hold up to harsh conditions. Rain or shine, sleet or snow, your equipment needs to keep up with you.
