The YSI 600R provides water quality sampling in a small package for both surface water and groundwater. With less than a 2-inch (4.2 cm) diameter, the 600R easily fits into wells. This sonde measures dissolved oxygen using the Rapid PulseTM stirring-independent dissolved oxygen sensor, conductivity, temperature, and pH. The pH reference electrode is field-replaceable.

The YSI 600R interfaces with the YSI 6500 Environmental Process Monitor, the YSI 6200 Data Acquisition System, and many other data collection platforms for long-term unattended monitoring; and with the YSI 650 Multiparameter Display System for sampling.

All YSI 6-Series sondes can be used with YSI EcoWatch for Windows software. EcoWatch is communication and data processing software that is fast and easy-to-use. You'll see the whole picture with a single program, obtain statistics easily, merge data files, and run large studies.
