The instrument add calibrator into the reaction cuvette.The SIP injection pump aspirate the calibrator,
and pump it into the Na、K、Cl electrode pipeline of the reaction tank. Test the electric potential on the
basis of reference electrode. The sample probe aspirates sample and diluent, and pump it into the
reaction cuvette. Test the electric potential, and the concentration can be calculated.
