Analyzers of electrolytes Audicom, manufactured by Jiangsu Audicom Medical Technology Co., Ltd. (China), are fully automatic instruments with a capacity of up to 65 tests per hour. They are used for quantitative determination of sodium, potassium, chlorine, calcium and pH ions in whole blood samples, serum, plasma, diluted urine, control solutions. These devices combine economy and reliability, ease of operation and high accuracy. Analyzers can be used in laboratories and in hemodialysis units. One of the main advantages that distinguish Audicom analyzers from existing analogues is the use of reagents in separate packages, rather than in packs, which makes it possible to replace each reagent separately as it is fully used. In this case, the user receives a real reduction in the total consumption of reagents and, accordingly, a significant reduction in the cost of the study. Electrodes have a long service life, do not require special maintenance, provide maximum accuracy and reliability of measurement. The manufacturer gives a guarantee for electrodes for 12 months. The average service life of electrodes is more than 2 years, and the maximum service life can be up to 5 years.
