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.
Conductivity is a measure of waterâs capability to pass electrical flow. This ability is directly related to the concentration of ions in the water 1. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds 3.
The electrical conductivity of a solution of an electrolyte is measured by determining the resistance of the solution between two flat or cylindrical electrodes separated by a fixed distance. An alternating voltage is used in order to avoid electrolysis. The resistance is measured by a conductivity meter.
