Fighting Fouling: Extending Sonde Deployment Times with EXO’s Wiped C/T Sensor

Here at YSI, we’ve been hard at work over the past several years finding ways to push the limits of how long our sondes can monitor water quality out in the field without maintenance. Learn more about how our latest sensor can reshape your SOP.

The new EXO Wiped (C/T) Sensor (599827)

YSI, a Xylem brand is excited to announce the new EXO Wiped Conductivity/Temperature Sensor (599827) is set to launch on October 19th, 2015!

UNSW uses on-line monitoring of cyanobacteria in source water treatment.

Members of the University of New South Wales (UNSW) bioMASS Lab, under the auspices of the Australian Research Council (ARC), have recently started executing the “Linkage Project” – a coordinated effort to better monitor cyanobacteria in important local watersheds.  On-line information gathered from this project will be used to predict coagulant doses and powdered activated […]

EXO’s Superior Durability – Alaskan flood waters fail to put a dent in the EXO platform.

The Crooked Creek Watershed, located north of Fairbanks, runs through some 300 square miles of Alaska’s central interior. In the past, this area was a hotbed for placer gold mining, but modernity has changed the landscape into a collection of humble creeks, sleepy rural communities, and some small scale mining operations. Crooked Creek Watershed is […]

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 […]

fDOM Profiles Probe Color Change in Drinking Water Reservoir

Recently, James Chen, an application specialist from Xylem Analytics China, collected and shared water quality data from a reservoir in Xi’an, a western city in China in the Weihe River Basin area. During the wet season, water in the reservoir appears to change color with the influx of river water at one end of the […]

Reduce Calibration Standard Use with EXO Concurrent Sensor Calibration

In this video you will discover one of the many smart features of the EXO advanced water quality monitoring platform, designed to save you money and time. When you calibrate water quality sensors, you can now put together several of the same-parameter sensors on the same sonde at the same time, thus saving the amount […]

fDOM Data Aids Water Quality Restoration in Everglades Stormwater Treatment Areas

With decades of residential and agricultural growth, the levels of phosphorus, nutrients and other pollutants entering the Everglades ecosystem is on the rise. The South Florida Water Management District has undertaken a number of programs to protect the ecosystem and achieve better water quality, including a series of Stormwater Treatment Areas (STAs or constructed wetlands). […]

Replaceable Reagent Module Reduces Total Cost of Ownership of EXO Sensors

EXO pH, pH/ORP, ammonium, nitrate and chloride sensors have a unique design that incorporates a user-replaceable sensor tip (module) and a reusable sensor base that houses the processing electronics, memory, and wet-mate connector. This allows users to reduce the costs associated with these sensors by only replacing the relatively inexpensive module periodically and not the more […]
