YSI EXO3s Multi-Parameter Water Quality Sonde – NexSens
The YSI EXO3s is a compact, batteryless sonde that comes with the same capabilities as the EXO3, and is ideal for specialized applications where external power is supplied.
Details
Overview
The YSI EXO3s represents an advanced sonde platform that offers a wide range of capabilities to those dedicated to monitoring natural aquatic environments such as oceans, estuaries, rivers, lakes, and groundwater. With a highly efficient power management platform, robust construction and chemistry-free anti-fouling system, EXO allows accurate data collection for up to 90 days between service intervals.

Onboard Signal Processing and Memory
All EXO sensors are digital sensors with onboard signal processing and memory. Built-in sensor diagnostic and calibration data allow users to calibrate multiple sensors in one sonde and distribute them to various other sondes in the field. Wet-mateable connectors allow for swaps in wet conditions, while active port monitoring automatically detects each sensor and verifies operation.
