Cargozippers successfully adds Salinity,Conductivity and Total Dissolved Solids parameters to their Pond Monitoring Solution

We are pleased to announce additional suite of sensors to our Pond monitoring Solution adding to our already existing standard configuration of sensors, namely Temperature, Dissolved oxygen, PH levels

The sensors we have added to our Solution are:

  • Salinity
  • Conductivity
  • Total Dissolved Solids


Salinity refers to the total concentration of dissolved ions in water, the major contributors being calcium, sodium, potassium, bicarbonate, chloride and sulfate. Salinity is usually reported as parts per thousand (ppt, grams of salt per kilogram of water). The salinity of natural waters tends to reflect
the climate, geography and hydrological conditions of the immediate surroundings. Each aquatic species has an optimum range of salinity for reproduction and growth, although the salinity tolerance of most aquaculture species is rather broad. For example, rainbow trout fingerlings are produced infreshwater, acclimated to saltwater and then grown out to marketable size in sea cages at salinities as high as 20 ppt. Most freshwater fish of importance in aquaculture reproduce and grow well at salinities up to a least 4-5 ppt.
Osmoregulation is the process of maintaining the concentration of dissolved salts in the body fluids by regulating the uptake of ions from the environment and through the restriction of ion loss. Freshwater fish for example tend to accumulate water because they have body fluids more
concentrated in ions than the surrounding water. When exposed to salinity values outside of their optimum range, aquatic species must spend considerable energy for osmoregulation at the expense of other functions, such as growth. If salinity deviates too far from optimum, the animal cannot
maintain homeostasis and dies. The blood of freshwater fishes has an osmotic pressure approximately equal to the osmotic pressure of a 7 ppt sodium chloride solution. Often times to reduce stress and reduce energy required for osmoregulation, freshwater aquaculture systems are
maintained at 2-3 ppt salinity.

CZIOT Pond Monitoring Solution provides aquaculture trade to monitor any uncontrolled changes in the Salinity level.

Conductivity and TDS:

Conductivity is a measure of water’s capability to pass electricity flow. This is directly related to the concentration of ions in the water. These conductive ions come from salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds. Compounds that dissolve into ions are also known as electrolytes. The greater number ions that are present, the higher the conductivity of water. Likewise, the lesser ions that are in the water, the less conductive it is. Distilled or deionized water can act as an insulator due to its extreemly low conductivity value. Sea water, on the other hand, has a very higher conductivity.

Total dissolved solids (TDS) is an indicator of the total content of all inorganic and organic substances contained in a liquid in molecular, ionized or micro-granular suspended state. Generally, the operational definition is that the solids should be small enough to survive filtration using a filter with two-micrometer (nominal size, or smaller) pores. Total dissolved solids are discussed only for freshwater systems, as salinity is  included some of the ions comprising the definition of TDS. The principal application of TDS is in the study of water quality for streams,rivers and ponds. Although TDS is not generally considered to be a primary pollutant (e.g. it is not assumed to be associated with health effects) it is used as an indication of aesthetic characteristics of drinking water and as an total indicator of the presence of a broad array of chemical contaminants.
