## What is AquaViewer II?

The YSI AquaViewer II App displays current and logged data
acquired from YSI continuous monitoring and control aquaculture
instruments - the 5200A, 5400 and 5500D. The app helps you
keep a close watch on the water quality conditions at your facility.
The app makes it easy for aquaculture and aquatic life support
system operators to monitor the water quality of their facilities,
even when they are away from the facility. Water quality data are
updated every 10 seconds giving the operator precise, real-time
information. Additionally, data is logged every 10 minutes to a
secure, cloud-based server provided by YSI/Xylem.
