Libelium’s catalogue continues to grow with new sensors. Manta (Eureka), and Stacsense (Aqualabo) have been added to the broad family of sensors integrated with our technology, both specifically for IoT water solutions.

The Manta sensor is a multiparameter probe with two models. The Manta+ 30 comprises one of the most frequently requested configurations – of temp, pH, conductivity, optical DO, and turbidity (with optional depth and ORP). While the Manta+ 35 measures PAR, chlorophyll, blue-green algae, rhodamine, crude and refined oil, CDOM/FDOM, fluorescein dye, optical brighteners and tryptophan, to which add other parameters such as sodium, ammonium, nitrate, chloride and TDG.

StacSense is a new optical digital sensor for measuring biological parameters. It’s a multiparameters probe which can simulataneously measure: SAC254, COD, TOC, BOD, Turbidity for clear water and sewage water applications.

Water and wastewater flows generally contain a large number of components. It is not possible to analyze each substance individually. Therefore, the user determines the organic load using parameters such as COD, BOD, TOC and SAC254.

  • COD – Chemical Oxygen Demand measures the amount of substances that can be oxidized by chemical means that are dissolved or in suspension in a liquid sample. This includes organic and inorganic substances. It is used to measure the degree of contamination and is expressed in milligrams of diatomic oxygen per liter (mg O2 / l). It is mainly intended to measure the concentration of organic matter in the water.
  • BOD – Biological Oxygen Demand measures the amount of oxygen consumed by degrading the organic matter in a liquid sample. It is used to properly measure the degree of contamination. It is expressed in milligrams of diatomic oxygen per liter (mg O2 / l). BOD is similar to COD, but, while the COD is less specific, as it measures everything that can be chemically oxidized, the BOD measures only what can be biologically oxidized.
  • TOC – Total Organic Carbon is the amount of carbon bound to an organic compound in a water sample and is frequently used as a non-specific indicator of water quality. The carbon present in natural and wastewater is made up of a variety of organic compounds in various stages of oxidation. Some can be further oxidized by chemical or biological processes, and BOD and COD methods can be used to distinguish these compounds. Since TOC is independent of the oxidation phase of organic matter and does not measure inorganic matter that can contribute to COD, the TOC method cannot replace COD or BOD methods.
  • SAC254 is the coeffecient spectral absorption at 254 nm (ultraviolet). A consolidated method for monitoring organic load is the measurement of this parameter, since many organic substances absorb UV light at that wavelength.
