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.
EC is a measure of the concentration of dissolved ions in water, and is reported in Âµmhos/cm (micromhos per centimeter) or ÂµS/cm (microsiemens per centimeter). A Âµmho is equivalent to a ÂµS. EC can be measured in a laboratory or with an inexpensive field meter. Also called specific conductance or specific conductivity.
