Question

what is calibration of electrical conductivity meter

Answer 1

A conductivity meter measures an aqueous solution's ability to transmit an electrical current. A solution's conductivity is affected by the ions in solution and temperature. To measure conductivity, a conductivity meter uses a probe with four electrodes. The meter passes an alternating current between electrodes and measures the potential between the inner pair. By using the known distance between electrodes and Ohm's law, the meter then computes the conductivity of the solution being tested. Some meters use inductive-coupled coils instead of four electrodes.
