EXO GO Wireless Communication Device EXO3 Multiparameter Sonde EXO2s Customized Sonde The enhanced interface for EXO [eBook] Global Explorers: Navigating Climate Data

EXO GO Wireless Communication Device

Sample and deploy anywhere,
utilizing the full power of KorEXO Software!


EXO GO is a wireless communication device that interfaces with EXO Sondes using any Windows OS tablet or PC for sampling and monitoring applications.

EXO3 Multiparameter Sonde

The parameters you need, without the features you don’t!

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.

EXO3 is a purpose-built sonde for monitoring major water quality parameters, including: pH, conductivity, temperature, turbidity, and dissolved oxygen.

EXO2s Customized Sonde

The more maneuverable monitoring platform.

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, and is ideal for specialized applications.

The enhanced interface for EXO

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. Introducing the updated EXO Handheld from YSI, designed and engineered as a dedicated interface to EXO sondes. Log real-time data, calibrate sensors, set-up sondes for deployment, and transfer water quality data to a PC with this feature packed device.

[eBook] Global Explorers: Navigating Climate Data

No single topic touches as many aspects of the YSI business as climate science. The instruments we build are used in every environment on Earth—on glaciers and pack ice, in the tropics, in springs, rivers, lakes, estuaries and oceans. In this free eBook, learn how the vast streams of data these instruments collect provide us with a snapshot of the health of our planet.

Application Story: EXO2 Monitors Climate and Water Quality Dynamics in Agro-Ecosystems

In eastern Iowa, agriculture is the predominant land use, with upwards of 90% of the land surface dedicated to production. Multiple ongoing studies at the University of Iowa are focused on the interaction of the agricultural system with climate dynamics to produce both water quality and quantity responses.

Future Proof: I need technology that works now and ten years from now

A common challenge faced by the water monitoring community is taking the risk of investing in equipment when future needs, projects and funding are in flux. Which water quality instrument can you rely on for the next decade? Is there a way to future-proof your decision? There are a lot of outside forces that can […]

A Site for Science: Water Instrumentation Provides Insight for Ecological Research

Multiple scientific studies have been conducted on the water, organisms and food webs in Calder Lake over the past 50 years. Calder Lake, a natural 10-acre mesotrophic lake, is located on the property of the Louis Calder Center, a biological field station of Fordham University in New York. To further its research, the Louis Calder […]

Effective 6-Month Deployment in Marine Waters

The EXO2 water quality sonde was deployed alongside an Aanderaa Seaguard instrument under the cold saltwater of the Koljoe Fjord in Sweden. Water temperatures from October to May ranged from 0 to 12ºC (32 to 54ºF). The EXO2 sonde recorded data every hour for 180 days, and was equipped with the following sensors: optical dissolved oxygen, […]

EXO Extended Range Turbidity Sensor

For those measuring turbidity for storm water, construction run-off, flood events, TMDLs or other water quality concerns, YSI offers the EXO submersible field sensor to make accurate and extended range (0-4000 FNU) turbidity measurements in marine and fresh waters for water quality sampling and monitoring. What Is Turbidity? Turbidity is the indirect measurement of the suspended solid […]

Nitrate, Ammonium and Chloride Sensors for Freshwater Measurements

YSI has released nitrate, ammonium and chloride sensors for the EXO advanced water monitoring platform. The guarded sensors are well-suited for freshwater applications down to 17 meters. Possible uses include spot checks and sampling in streams, rivers, lakes, ponds and ground water. The sensors can also be used in short-term continuous monitoring applications. Nitrate forms […]

A Little Biofouling Can Go a Long Way—to Screwing Up Your Data

Biofouling. The bane of existence for many monitoring programs. Even a little spot of the stuff on water quality sensor optics can affect your data. Case in point: Individual wipers on each of these sensors (photo below) are doing a pretty good job at cleaning the sensor optics. But notice the small ring of soft […]
