LOW-CONDUCTIVITY CONTACTING-TYPE CONDUCTIVITY MEASUREMENT |
摘要 |
A method (100) of measuring low conductivity of a liquid sample using a contacting- type conductivity sensor is provided. The method (100) includes applying a first excitation current (102) to a contacting-type conductivity sensor at a first drive frequency. A first voltage response to the first excitation current is determined (104). A second excitation current (106) is applied to the contacting-type conductivity sensor at a second drive frequency higher than the first drive frequency. A second voltage response to the second excitation current is determined (108). A conductivity output is provided based, at least in part, on the first and second voltage responses (110). A system for measuring conductivity of a liquid at or below 100 mu8/alphaeta is also provided (10). |
