This electrolyte analyzer is suitable for measure of the contents of K+, Na+, Cl-, Ca2+ in the samples of human serum, plasma (whole blood) and diluted urine and pH value (only for use of calibrating calcium ion, not for result of human acid-base balance) and for providing the results of standardized ionized calcium (nCa), total calcium (TCa) through calculation. It can also determine the contents of K+, Na+, Clin the diluted urine. This electrolyte analyzer is used for measure of ion in clinical samples with ion selective electrode. The above-said data can be rapidly and accurately measured. The analyzed results shall be displayed in LCD display and printed on the sample report by inbuilt printer. Contraindications: none.■ Power-supply voltage: 100-240V～, 50Hz±1Hz, 85VA. ■ Equipped with earthed socket. Ground connection should be reliable (It is very import for safety and stable operation). If voltage is beyond requirement, external voltage-regulated power supply should be supplied. ■ The place where instrument is installed has not strong electromagnetic interference. If it can not be eliminated, the place for installation should be changed ■ The installation location for instrument should be spacious and the loading requirements of instrument installation on desktop or ground are more than 100kg/m 2 to ensure that it should be convenient for operator to switch off the power in urgent situation. If even it is limited for conditions, the power switch should be 25cm far from surrounding articles, such as wall. ■ Environment temperature: 10℃～30℃; Max relative humidity: no more than 85%. ■ Dispose the waste in accordance with relevant local regulations, It’s OK to use the plastic bottle with same function as original waste liquid bottle if the waste liquid bottle is lost. Clear waste liquid in a time according to the relevant requirements of the country. Note: The instrument cannot be switched on only after it is switched off for five seconds at least to avoid damaging because of current rush.Electrolyte analyzer is packaged in cases: Main unit, accessories of electrolyte Analyzer . Package case should be carefully handled to avoid damaging. If case is damaged or parts are lost, please notify the supplier immediately.
