YSI 6820/6920 V2
Water Quality Sonde with Flow Cell
Featured Rental
Our most popular YSI sonde rental, the 6820 and 6920 are capable of measuring and logging up to 16 parameters. Sonde rentals always include a flow cell making them useful for either downhole monitoring or whenever water is pumped. Incredibly versatile, we carry these 6 series sondes in multiple configurations with all the standard ports, 3 ISE ports, and either 1 or 2 optical ports for use with the full line of available YSI probes. Every YSI 6 series sonde rental also includes the 650 MDS display for viewing data either logged previously or in real time. An SDI-12 interface allows integration into almost any telemetry system. The 6820 is powered by 650 MDS display and is useful for real time or flow cell monitoring. The 6920 is self powered making it capable of unattended monitoring when there is no power on site.
