All sondes are calibrated before they leave our office. Calibration is only needed if renting for a long period of time. If necessary, a Fondriest representative can walk you through the calibration process assuming you have the required buffers and standards available.
The EXO1 sonde rental does not come with an EXO display. The display can be rented at an additional cost.
The EXO1 has a battery life of approximately 90 days at a 15-minute logging interval and uses (2) D-Cell Batteries.

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.
