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 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 EXO’s Central Wiper. 

Discover the benefits of Wiped (C/T):

Save money by reducing the number of site visits each year. Pays for itself in under a year depending on application. 
 

Lower the cleaning & maintenance requirements for conductivity sensors, and spend less time with anti-fouling screens and removing the build-up of hard growth.

Improve the reliability of your conductivity sensor, now with non-metallic electrodes. Leverage the flexible, plug-and-play sensor architecture of an existing EXO2 or EXO3 sonde with this user upgradeable solution. 

Improve the representativeness of your conductivity data by avoiding stagnant readings and reducing the impact of micro-environments.
 

Reduce the need for post-processing data and spend less time manually adjusting for fouling-related sensor drift.
 

Prevent common types of fouling from impacting your valuable data, including; particulates, algae, barnacles, and trapped gasses.

Wet-mateable connectors allow for swaps in wet conditions, while the smart ports shut down any excessive current draws to prevent damage.

Designed for Use with EXO Multiparameter Sondes
• EXO1 sonde has 4 ports and a smaller diameter
• EXO2 sonde has 7 ports for the ultimate monitoring platform
• EXO3 sonde has 5 ports for a lower cost option using the central wiper
• EXO2s sonde offers the same features as the EXO2, but without the battery compartment

• Dual-channel sensor
• Measures and outputs both chlorophyll & blue-green algae
• Options for µg/L and RFU outputs

Compact and Accurate
The EXO platform offers a completely new approach - highly accurate, quick-response sensors in a small, easy-to-deploy and easy-to-maintain package. Gone are large and complicated sensor arrangements requiring complex integration.
