Cell Constant (K) and Automatic Conductivity Calibration

Versa Star Pro meters with a conductivity module are capable of automatically recognizing
Thermo Scientific Orion 100 μS/cm conductivity standard, 1413 μS/cm conductivity standard
and 12.9 mS/cm conductivity standard when the nominal cell constant (K) value of the
conductivity probe is entered in the setup menu.
