Intelligent measuring buoys for precise water monitoring


 Our modular measuring buoys, equipped with the energy-efficient Aquatos Web internet data logger and versatile SDI-12 sensors, enable long-term, low-maintenance monitoring of a wide range of water parameters – reliably and regardless of location.


Core functions:

  • Modular design: Allows the integration of different sensors as required.
  • Energy efficient: Long battery life for self-sufficient operation.
  • Robust construction: Durable stainless steel housing for use in demanding conditions.
  • Real-time data transmission: Reliable remote monitoring through continuous data transmission.


Monitorable parameters:

  • Water temperature
  • Oxygen content
  • Electrical conductivity
  • turbidity
  • pH value / redox potential


Our buoys are suitable for a wide range of applications. Installation is simple and can be completed in under an hour.

Bathing and recreational waters – early warning systems


Oxygen content, pH, and temperature are measured to identify critical environmental conditions. Conductivity serves as an indicator of nutrient inputs or pollution.

Stratification monitoring in lakes (thermal stratification)


 Vertical temperature profiles using measuring chains provide data on stratification and visibility. This is helpful for assessing oxygen depletion in deep water and for measures such as aeration or lake remediation. Water level measurement in standing and flowing waters.


Recording of water level fluctuations to support flood protection, watercourse development and the operation of artificial reservoirs.

Environmental monitoring in protected areas

Self-sufficient measuring station for remote or sensitive natural areas.

 The compact design enables trouble-free operation in harmony with flora and fauna. Municipal water management: Integration into existing monitoring systems, e.g., for controlling stormwater discharges or industrial influences. Supports compliance with legal requirements such as the EU Water Framework Directive.


 Research and Teaching: Flexible platform for scientific studies, long-term limnological observations, or university projects. Expandable with additional sensors, e.g., for turbidity or redox potential.


Our buoy for lakes and larger bodies of water

Standard measuring buoy from TerraTransfer

Our shallow water buoy for measuring depths from 20cm

 Our innovative shallow water buoy was specifically developed for the challenges of shallow waters. Given the increasing demand due to changing climatic conditions, it enables reliable water quality monitoring even where conventional systems reach their limits.


Thanks to its compact and stable design, the buoy is ideal for use in lakes, ponds, wetlands, or slow-flowing rivers. It continuously provides precise measurement data on relevant environmental parameters for science, water conservation, and government agencies.


Advantages at a glance:


  • Specially designed for shallow waters
  • Robust construction for long-term use
  • Continuous data transmission and remote monitoring
  • Customizable with different sensors as needed
