The relationship between ionic concentration and conductance can be easily determined for most streams after an appropriate number of samples have been analyzed for dissolved solids and electrical conductance. 011713815 These sensors are known to be extremely precise and come with very little maintenance requirements. The main measurements of electrical conductivity are uS/cm and mS/cm, the former of which is considered to be less than the latter. These models come with a heavy-duty, stainless-steel body and can accommodate a maximum temperature of 200 degrees Celsius. Aquameter® - UK Trade Mark Registration No. The probe that is inserted into the water sample applies a voltage between electrodes.
But opting out of some of these cookies may have an effect on your browsing experience. When the EC of water is higher, electricity will be more attracted to water, which is why it can be dangerous to use a smartphone while taking a bath or to go for a swim while a thunderstorm is ongoing. This ability of conductance in water is directly proportional to the concentration of the ions present in the water. Your email address will not be published. 0000009103 00000 n As for mS/cm, this unit is essentially equivalent to 100 micro-Siemens per one S/CM. The conductivity of water refers to the ability of water to conduct an electrical current. The electrical conductivity of the water depends on the water temperature: the higher the temperature, the higher the electrical conductivity would be. The use of electrical conductance as a water quality indicator is good for estimating the amount of mineralization and is commonly used for total dissolved solids. 00003000627 Are you sure you want to leave?
Some of the more common uses of EC testing equipment occur with environmental testing, in cooling towers, in boilers, and in laboratories with pharmaceutical testing. 2020 © SMART Fertilizer Software. And, If the measurement is done at different temperatures and later corrected to the temperature of 25° C, then it is called as the temperature coefficient. Many EC meters nowadays automatically standardize the readings to 25oC.While the electrical conductivity is a good indicator of the total salinity, it still does not provide any informati… Please, leave your email to continue reading. The natural impacts on EC in water are rain, geology and evaporation. Ans: Saltwater is conductive due to the presence of Sodium and Chloride(NaCl) ions in it.
