First Midwest Bank Of Poplar Bluff's routing number (the leftmost number on the bottom of a check) is 81519510. Sometimes, banks have multiple routing numbers for different branches or uses. Please make sure this is the correct routing number for your branch!
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.
Resistivity / Conductivity Measurement of Purified Water Most laboratory water purification systems contain a resistivity or conductivity meter and cell to monitor the purity level of the water. Resistivity is the reciprocal of conductivity and either may be used to inexpensively monitor the ionic purity of water. Resistivity or conductivity of water is a measure of the ability of the water to resist or conduct an electric current. The ability of water to resist or conduct an electric current is directly related to the amount of ionic material (salts) dissolved in the water.
