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.

Features Include:

  • YSI manufactures buoy, instruments, and loggers for a complete, integrated solution
  • Customizable with third-party sensors
  • Uniform color doesn't require regular maintenance
  • Through-hull penetration for monitoring equipment makes routine servicing simple, fast, and secure
  • Standard configurations available with short lead time
  • Virtually indestructible buoy hull survives impact, ice, and punctures

Options & Accessories:

  • Meteorological Package - Additional parameters to complement your monitoring program
  • Wireless Data Transmission - Several options to wirelessly transmit data are available, ask us which suits your application best
  • Satellite Communications - Either Iridium or GOES telemetry can be fitted on this system
  • Current Profiling - Can be combined with a Current Profiler, either bottom mounted or downward looking
