YSI EMM2.0 - Coastal Buoy

The YSI EMM2.0 is one of the most versatile and reliable buoy solutions on the market. These buoys have been deployed with wet-chemistry nutrient and metal analyzers, current meters, water quality monitors, GPS, atmospheric sensors, wave sensors, hydrocarbon sensors, and more. The stable platform can be easily customized to maximize instrumentation on a single monitoring platform. Adding satellite, radio, or cellular telemetry provides data to a custom visual display, making it easy for researchers and operators alike to receive critical data on a daily basis.

YSI EMM25 - Sonde Spar

Looking for a cost effective way to deploy a water quality sonde? The YSI EMM25, Sonde Spar is designed to be a low cost option for short and long-term monitoring. It's simple to use design allows for rapid deployment for event monitoring and emergency response. The lightweight design allows for the system to be deployed by a single person; it can be deployed from a small boat or from shore. The integral deployment tube will accept any YSI EXO or 6-Series sonde or 3rd party device.

Available options for the EMM25 Sonde Spar include an amber, self-contained flashing beacon for deployments in navigable waters. Bluetooth connectivity for remote data access from a compatible Bluetooth enabled device.

YSI EMM68 - Harbour Buoy

The Harbour buoy provides a quickly deployable water quality monitoring platform with remote telemetry. The system can be lifted by two people. And it is completely serviceable from a small boat.

Remote data delivery keeps you informed of changing conditions as they occur, such as storms, discharges, CSOs, TMDLs, dredging, and construction. Collect data in waters as shallow as 1.8 meters.

YSI EMM700 - Bay Buoy

With more free-board and greater load capacity, this buoy supports a wide array of water quality instrumentation and other systems. Heavy-duty, lightweight foam hull withstands collisions and harsh conditions in lakes, ponds, rivers, reservoirs, and near coastal applications. The YSI Bay Buoy is easy to handle and can be deployed from most small vessels.

YSI EMM350 Pisces Lightweight Pontoon

The YSI EMM350 Pisces is a lightweight pontoon platform which supports water quality, water velocity, and meteorological sensors, as well as computer logging systems.Housing it's payload are two topside aluminum chests that contain the data acquisition system, cellular modem, and battery. The chests are easily serviceable from the water and accommodate multiple underwater cable connections.

Sailbuoy ASV Platform with Aanderaa Smart Sensor Suite

By utilizing the power of the Aanderaa Smart Sensor Suite and the wind and solar driven "Sailbuoy" from Offshore Sensing, a new cost-efficient easily handled autonomous platform has been developed. The Sail buoy Water Quality Monitor (WQM) is designed for easy handling during shipment, deployment, data collection and recovery. The Sailbuoy WQM has been extensively field-tested and demonstrated excellent long-term monitoring.
