FAQ
QHow is the Conductivity Meter calibrated with standard liquid?
A
The electrode is immersed in the standard solution and the temperature of the standard solution is controlled at 25 +/- 0.1 ° C. Standard solution selection: electrode coefficient 0.1 can be used for standard solution of 146.6 μs/cm, electrode coefficient 1.0 can be used for standard solution of 1408 μs/cm, and electrode coefficient 10 can be used for standard solution of 12.85ms/cm or 111.3ms/cm. The current conductivity measured standard solution result K is known, the standard solution conductivity is 1408μS/cm, and the re-calibrated electrode Changshu J is unknown. J known/K known = J unknown/1408
