Electrolyte analyzers are indispensable in clinical testing. In clinical practice, it mainly tests and maintains the balance of osmotic pressure in human blood and body fluids; in surgery, burns, diarrhea, acute myocardial infarction and other patients who need a large amount of balanced fluid replacement, the test and detection of ions are very important. EA Series Electrolyte Analyzers are highly precise and accurate, providing accurate, reliable, fast, and easy-to-use results for any sample. Therefore, ion detection is an essential general equipment for hospitals at all levels.
