When To Call a Doctor. Call or other emergency services immediately if you have vertigo (a spinning sensation) and: 1  You passed out (lost consciousness). 2  You have symptoms of a stroke, such as:  Sudden numbness, tingling, weakness, or loss of movement in your face, arm, or leg, especially on only one side of your body.
High quality deionized water has a conductivity of about 5.5 Î¼S/m, typical drinking water in the range of 5-50 mS/m, while sea water about 5 S/m (i.e., sea water's conductivity is one million times higher than that of deionized water).n alternating voltage is used in order to avoid electrolysis. The resistance is measured by a conductivity meter. Typical frequencies used are in the range 1â3 kHz. The dependence on the frequency is usually small, but may become appreciable at very high frequencies, an effect known as the DebyeâFalkenhagen effect.
Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is siemens per meter (S/m).n alternating voltage is used in order to avoid electrolysis. The resistance is measured by a conductivity meter. Typical frequencies used are in the range 1â3 kHz. The dependence on the frequency is usually small, but may become appreciable at very high frequencies, an effect known as the DebyeâFalkenhagen effect.
