In a hiring freeze, an employer decides to stop hiring employees for all non-essential positions. It allows an employer to consolidate current employees and potentially restructure departments to complete the work that is essential for serving the customers of the business.
Since the electrical conductivity is a measure to the capacity of water to conduct electrical current, it is directly related to the concentration of salts dissolved in water, and therefore to the Total Dissolved Solids (TDS). Salts dissolve into positively charged ions and negatively charged ions, which conduct electricity.
Most commonly, a special type of conductivity, called specific conductivity, is used. Conductivity Technology. Conductivity and salinity are both measured by an electric probe on the data logger. This probe measures how much electrical current moves through the water. Salinity is then calculated from this value. Conductivity is determined by measuring how easily an electrical current flows between two metal plates.
