Webinar | Fighting Fouling – 7 Tips to Extend Sonde Deployments

Learn the steps you can take to prevent Mother Nature from creating havoc with your data quality, and discover what new technology is available with the EXO Sonde Platform that will extend sonde deployments longer than ever before.

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.

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 […]

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, […]

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 […]

Reduce the Number of Field Service Trips with Improved Biofouling Protection

For most users, field servicing of water quality sensors is a significant part of their monitoring budgets. And a reduction in the number of field servicing trips can have a huge cost savings. YSI has been testing the EXO sondes at some pretty fouling intensive sites over the past 12 months. One of the goals […]

Field Tests Show Strong Agreement Between EXO and 6-Series Time-Series Data in South Carolina Estuary

In March 2012, YSI (a Xylem brand) released its next-generation water quality sonde, the EXO2, which represents a number of advances in sensor and anti-fouling technology. To ensure that a transition to the EXO2 would not introduce discontinuities into long-term data sets established with existing YSI 6-Series sondes, a field comparison of the two sonde […]
