What is mmho?

MMHO stands for "Millimhos per centimeter". It is a unit of electrical conductivity or specific conductance used to measure the ability of a solution to conduct electricity. Specifically, it measures the number of millimhos of electrical conductance per centimeter of the distance between two electrodes in the solution. MMHO is commonly used in scientific and industrial applications, particularly in the field of water quality testing, to determine the level of dissolved ions or salts in a solution. A high mmho value indicates high conductivity, which may be an indication of contaminants or dissolved minerals in the water.
