The YSI 6951 Pontoon Vertical Profiling System offers user-programmable sample intervals, redundant error recovery logic that detects unexpected activity and recovers automatically, and is compatible with all YSI EXO and 6-Series sondes equipped with depth.

Fixed - Vertical Profiling System

YSI 6950 Fixed - Vertical Profiling System

Mountable on a dam, pier, piling, or other stationary location, the 6950 offers user-programmable sample intervals with wireless transmission options. The YSI 6950 is compatible with all YSI EXO and 6-Series sondes equipped with depth, and comes with Profile Wizard software for easy set-up and deployment.

SmartSub Observatory

Aanderaa SmartSub Observatory

Smart Sub Observatory is a flexible platform enabling tailor-made solutions, both with sensors from Aanderaa and other suppliers. They can be used off-the-shelf or customized to better cover application requirements.

YSI 5200A

YSI 5200A Multiparameter Monitoring and Control Instrument

Designed specifically for Aquaculture Systems, the YSI 5200A and AquaManager™ Software integrate process control, alarming, and data management into one product. Simple enough to monitor one tank, powerful enough to manage a full scale farming operation from anywhere in the world. Simultaneously measure dissolved oxygen, pH, conductivity, ORP, salinity and temperature.

Aanderaa Conductivity Sensor 4319

Aanderaa Conductivity Sensor

Conductivity sensors from Aanderaa are compact, fully integrated sensors for measuring the electrical conductivity of seawater. Conductivity is a key parameter for in-situ measurements of several fundamental physical properties of seawater.

Aanderaa Doppler Current Profiler Sensor 5400

Aanderaa Current Sensor

The Aanderaa Doppler Current Sensor (DCS) is a rugged, true vector averaging sensor for measuring current speed and direction in the sea. The sensor has built-in compass and tilt sensor and may also output sea temperature. 

Aanderaa Aqua Optode 4531

Aanderaa Oxygen Sensor

The Aanderaa Oxygen Sensor was the first and only to measure dissolved oxygen for years without drift. Now it is one of the fastest!

Aanderaa Oxygen Sensor is designed to measure absolute oxygen concentration and % saturation. The oxygen optode can be used from streams to deep sea, from Aquaculture to Waste water and from Polar ice areas to Hydrothermal vents. The lifetime-based luminescence quenching principle offers the following benefits:

Aanderaa Pressure Sensor 4117

Aanderaa Pressure Sensor

Aanderaa pressure sensors are compact, intelligent pressure sensors designed for use on Aanderaa Data Instruments dataloggers as well as in other measuring systems.

MJK Expert™ 367

MJK Expert™ Hydrostatic Level Series

MJK offers a full series of water level transmitters designed for immersion in open tanks, wet-wells, ground water and reservoirs. The water level transmitters are designed for measurement under rough conditions in all water and wastewater applications with large concentrations of sludge and suspended solids.

Aanderaa Turbidity Sensor 4112

Aanderaa Turbidity Sensor

This measurement is known to have a good correlation to the amount of suspended matter in water and can be used to monitor e.g. sediment, algae or particle pollution. The sensor generates an output voltage proportional to the turbidity or suspended solids. The low power consumption makes it ideal for applications where battery drain is a concern.

Aanderaa Wave and Tide Sensor 5218/5218R

Aanderaa Wave & Tide Sensor

Aanderaa Wave and Tide Sensors are compact fully integrated sensor for measuring the wave and tide conditions designed to be mounted on the Aanderaa multiparameter SeaGuard Platform or via cable connected to SmartGuard datalogger.

Aanderaa GeoView web based display

Aanderaa GeoView Web Based Display

Aanderaa GeoView is part of the Aanderaa Real-Time Solution. This gives the user vast opportunities for interfacing meteorological, oceanographpic, or other environmental research equipment in a networked solution giving access to data real-time.


Aanderaa SmartGuard Datalogger

SmartGuard is the next generation sensor and instrument HUB for Ocean, Lake, Reservoir, Estuary and River Hydrometric stations. It's a complete observatory node for advanced Hydrologic/Meteorological stations as well as for small stand alone stations.

Storm 3 Datalogger

YSI WaterLOG Storm 3 Datalogger

The Storm 3 Data Logger incorporates a balanced set of inputs for analog, digital I/O and SDI-12 smart sensors to allow communication through cellular modems and GOES satellite. You'll love how easy it is to configure and collect data using the browser-based graphical user interface (GUI) with all standard web browsers on PCs, tablets and smart phones.

MJK chatter-lock

MJK Chatter Datalogger

Logging data far away from urban areas is handled by a battery powered datalogger, that gather information and send the information to a SCADA system, dedicated databases or even as e-mails when its suitable to do so.

Publicly placed dataloggers are vandal protected, and will send a warning when intruders act.

Sending data once a day will provide at battery life time of up to 5 years.

Information on ground water levels and early warning sewer systems in correlation with buildings nearby urban construction can save millions of Euros in damage.
