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.
Conductivity may be measured by applying an alternating electrical cur-rent (I) to two electrodes immersed in a solution and measuring the re-sulting voltage (V). During this process, the cations migrate to the nega-tive electrode, the anions to the positive electrode and the solution actsas an electrical conductor.
