YSI manufactures measuring devices for research on aquatic ecosystems as well as measurements in aquaculture water or waste water from settlements.

The oxygen meters from YSI have been used for years in Icelandic fish farming and have been well received.

YSI also manufactures multimeters for measuring oxygen, salinity, acidity and depth.

For the monitoring of various chemical and physical parameters in water and sea, YSI has developed deep probes that measure and collect information on salinity, oxygen, acidity, chlorophyll and other factors.

SonTek/YSI manufactures flow meters for rivers and canals as well as meters for current measurements in lakes and seas.

Endeco/YSI assembles the measuring devices into a system for remote monitoring of physical and chemical elements in air, lakes and sea.
