We have heard from customers who need the payload and capabilities of YSI?s best-in-class EXO2 sonde, but in spaces and places that can?t accommodate the EXO2. EXO2s is a customized, batteryless sonde that comes with the same warranty and capabilities as the EXO2, and is ideal for specialized applications such as:
? Attachment to an AUV or aerial drone
? Integration with a buy
? Horizontal profiling where light weight is optimal

The portability of EXO GO frees up your hands in the field. On-the-spot GPS coordinates and barometric pressure are viewed through the newest KorEXO Software running on both laptops and tablets. The device is IP-67 rated and highly ruggedized to withstand drops, drips, and dunks!.

Introducing the updated EXO Handheld from YSI, designed and engineered as a dedicated interface to EXO sondes. Log realtime data, calibrate sensors, set-up sondes for deployment, and transfer water quality data to a PC with this featurepacked device. Designed for reliable field use in challenging environmental conditions, this display features a waterproof IP-67, impact-resistant case and wet-mate connector.

The V2 sondes represent a proven generation of multi-parameter sondes from YSI. Perfect for harsh fouling environments, YSI's optical sensors feature an integrated wiper that prevents the impacts of biofouling, a corrosion-resistant titanium wiper shaft, and replaceable seals.
The YSI 6920 V2-2 sonde features an internal battery pack with memory for long-term, unattended deployments. Additionally, the sonde can be powered by a 650 display unit for spot sampling applications.

Designed for use in fresh, sea or polluted waters, the 600OMS V2 utilizes the field-proven YSI sensors and incorporates innovations in sensor configuration such as a conductivity and temperature module that fits into the sonde body.

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.

The EXO unguarded pH & ORP sensor is a digital smart sensor featuring welded titanium construction and wet-mateable connectors. Complete calibration in less than 15 minutes using EXO's suite of smart sensors and intuitive KOR interface software.
