Questions & Answers
What sensors does my EXO rental come with and do I need to calibrate them?

The EXO2 rental comes with temperature/conductivity, pH/ORP, Optical Dissolved Oxygen, Turbidity, and the central wiper installed and calibrated. Some sensors may need to be recalibrated during the rental depending on the duration.

Can I rent other sensors to use with my EXO sonde?

The total algae and fDOM sensors can be rented at an additional charge. ISE sensors (ammonium, nitrate & chloride) have a short lifespan (3-6 months), so they are not available for rent.

How should I store the EXO2 for shipping?

The goal of interim storage is to maintain a moist environment without submerging the sensors. Place 0.5in of water in the calibration cup and insert the sonde with all the sensors (remember to check to make sure unoccupied ports have a port plug). Close the calibration cup tightly to prevent evaporation during transit.

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.
