YSI EXO Central Wiper
The YSI 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.
Features
- Keeps the payload sensor faces clean using mechanical brush
- Prolongs deployments and improves data accuracy
- For use with EXO2 and EXO3 platforms only
- Expedited repair and warranty service
- Lifetime technical support

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
The wiper can only be installed in the center port of the bulkhead. A sensor can be installed in place of the wiper but not the other way around.
The wiper needs replaced when it has been worn or the brush begins to show splay. Actual wiper life varies from one deployment to another, but you can generally expect to get at least a year of use from a single brush.
No, the EXO central wiper can only be used with the EXO 2 and EXO 3 sondes.

Total algae sensor is the newest addition to YSI's EXO sondes
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.

YSI's fDOM sensor sheds light on organic matter
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.

YSI improves sonde technology with EXO
A new line of multiparameter sondes is making a splash in the water monitoring market. The recently introduced YSI EXO line offers simpler calibration, more rugged materials and a future-proof design. The new water quality sondes can measure temperature, conductivity, depth, dissolved oxygen, pH, ORP, total algae (chlorophyll and blue-green algae), turbidity and fluorescent dissolved organic matter. The EXO sondes carry Smart QC, which is a series of quality control checks that run automatically to help maintain calibration. Feedback from testing has confirmed that the checks cut down on wasted trips into the field due to setup or configuration errors.
