K+, Na+, Cl- and Ca++ are important constituents of blood. Only if these constituents are in normal range people can keep fit. SM-electrolyte analyzer is based on ISE (Ion selectivity electrode) for measuring ions, which is quick and accurate. Samples can be whole blood, serum, plasma and urine.
Please read the manual carefully before operation.

The principle of instrument is based on potentiometry between ion electrode and reference electrode. Most of the salt in electrolyte solution is in ion state. The electronic exchange between electrode and solution forms an electronic flow which represents the ion concentration.
