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 unit of measurement for conductivity is expressed in either microSiemens (uS/cm) or micromhos (umho/cm) which is the reciprocal of the unit of resistance, the ohm. The prefix micro means that it is measured in millionths of a mho. MicroSiemens and micromhos are equivalent units. Distilled water has a range of conductivity from 0.5 to 2 uS/cm. Drinking water is generally between 50 to 1500 uS/cm and domestic wastewater may have conductivities above 10,000 uS/cm.
