Chromophoric Dissolved Organic Matter or Colored Dissolved Organic Matter (CDOM): Both refer to organic matter in water that absorbs strongly in the ultraviolet (UV) spectrum. Fluorescent Dissolved Organic Matter (fDOM) refers to the fraction of CDOM that fluoresces. fDOM is a surrogate for CDOM, and a fast and easy means of tracking DOM in natural waters.
Measuring CDOM/fDOM is important because concentrations of CDOM affect submerged aquatic vegetation, coral reefs and other benthic communities.
Other fDOM applications include:
The EXO advanced water quality monitoring platform includes the versatile multiparameter EXO2 sonde for oceanographic, estuarine, or surface water applications. Collect data to 250m with the advanced EXO2 sonde – contains six replaceable 'smart' sensors and a central wiper to clean biofouling.
Capturing accurate data in fresh water, ground water and marine aquatic environments is easy with . The versatile multiparameter EXO1 sonde is ideal for estuarine, surface water, or ground water applications.
Instrument Only. Cables, probes/sensors, and accessories sold separately - please see the "Accessories" tab for details.
Offering the greatest value of any sonde available in the market, EXO3 combines the maneuverability of EXO1 with the powerful antifouling wiper of the EXO2. EXO3 is a purpose-built sonde for monitoring major water quality parameters, including: pH, conductivity, temperature, turbidity and dissolved oxygen.
The EXO fDOM (fluorescent dissolved organic matter) sensor is a digital smart sensor featuring welded titanium construction and wet-mateable connectors. Complete calibration in less than 15 minutes using EXO's suite of smart sensors and intuitive KOR interface software.
The brand new acoustic profiler joining the SeaGuard family. It features innovative development of the acoustic profiling capacity and an exceptional ability to collect high quality current information on moving and tilting moorings. Available as a self-recording instrument, it also integrates unique real time features to meet your application needs.
The RCM Blue is a self-recording Current Meter which measures water temperature in salt or fresh water, and a battery container with battery capacity up to 70Ah. The Doppler Current Sensor is an upgraded version of the proven SeaGuard ZPulse sensor. The instrument configuration and data retrieval is done via Bluetooth which eliminates the need to open the pressure case for repeated deployments.
The single-point SEAGUARD® RCM series is a completely new generation of current meters based on the SEAGUARD® datalogger platform and the ZPulse® multi-frequency Doppler Current Sensor (DCS). SEAGUARD® Products are based on modern technology and are the basic modules of our underwater observatory. They may be used as a multi-parameter instrument in the sea and in freshwater and feature a modular plug-and-play architecture.
