Overview
The EXO Central Wiper occupies the central port on an EXO2 or EXO3 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 or EXO3 sonde can be equipped with this anti-fouling wiper to prolong deployments and improve data accuracy.
Cost and Time Efficient
- Save money by reducing the number of site visits each year.
- Lower the cleaning & maintenance requirements for conductivity sensors
- Spend less time with anti-fouling screens and removing the build-up of hard growth
- Reduce the need for post-processing data and manually adjusting for fouling-related sensor drift
Reliable
- Improve reliability with non-metallic electrodes
- Avoid stagnant readings and reduce the impact of micro-environments
- Prevent particulates, algae, barnacles, and trapped gasses from impacting data

YSI EXO3s: The Latest in Water Quality Monitoring
The YSI EXO3s offers the latest in multi-parameter water quality monitoring equipment that has a comprehensive list of smart sensors. With an external power source, this sonde is a cost-effective, compact EXO that has the same capabilities as the EXO3 . The sonde is built to last with resilient materials and backed with vigorous testing. 
 
The device has five ports for available YSI EXO smart sensors or central wiper. It seamlessly integrates with a data logger to collect and push valuable data to the cloud for access from a PC or mobile device. This small sonde is exceptional for both sampling and continuous monitoring applications.

Many algae sensors can detect Chlorophyll a or levels of blue-green algae. YSI’s new Total Algae Sensor can measure both at the same time. 
 “If you’re only looking at Chlorophyll a, you can miss a very big portion of total algae biomass,” said Tim Finegan, product manager. 
 The new sensor is an optional attachment to the company’s line of EXO sondes, which debuted earlier this year. It’s an optical probe and maintenance is limited to keeping the sapphire windows on the unit clean. 
 The Total Algae Sensor can be calibrated in two different ways, one for spot sampling and one for continuous sampling, which allows users to make sure readings are accurate for their specific monitoring applications.

The new YSI EXO Sonde expands monitoring capabilities for users compared to YSI’s the previous generation of sondes. One new feature for the EXO is a fluorescent dissolved organic matter probe that measures light-absorbing particles in water. 
 
The sensor is another attempt by YSI to provide instrumentation options to those in the waste water industry, or anyone interested in measuring dissolved organic matter alongside other parameters. 
 
YSI’s fDOM sensor detects only on a narrow wavelength range. “The wavelength at which (particles) absorb light optimally and then the wavelength that they emit, or fluoresce light optimally, is unique to that molecule,” said Rob Ellison, YSI EXO director of research and development, during a webinar on the fDOM sensor.
