YSI EXO Sonde
The YSI EXO Sonde is a high accuracy water quality monitoring platform. Measures & logs: pH, EC, Temperature, Redox, DO & Turbidity simultaneously. When connected to telemetry, it will also report water level. So is the ideal instrument for marine, estuarine, surface and groundwater applications.
Contact Van WaltAdvantages
The EXO Sondes are very special and the result of a US $24 million investment programme. The idea was to create the ultimate water quality measuring device and no shortcuts were taken. The EXO’s have a host of features, viewable on the specification sheets but a few are worth focusing on:
- Wet mateable connectors. By the nature of their intended use, this type of device is rarely dry. This doesn’t matter with the EXO’s. Probes and cables can be disconnected and reconnected EVEN WHEN WET
- The electrodes are made of titanium for robustness and durability
- Calibration data is stored WITHIN THE ELECTRODES so spares can be pre-calibrated and exchanged on site without the necessity of returning the entire unit back to base for recalibration
