Features: Continuing calibration, the analyzer is always in a good situation ready for measurement at any time. This asures the accuracy of measurement results. The analyzer uses mutual bar formation electrode, reliable function, can replace the membrane and inner solution to lengthen the using time and lower the cost. Flushing solution can get rid of the dirty and reduce pollution to extend the use life of the electrode. This lowers the unit consumption and cost. The sampling case is transparent, the temperature, electrode drift and lack of calibrating solution can be showed automatically. The rich-contented servicing program provides operators many options(e.g. the channel breaks), so that operators judge the reason of the trouble. Inner thermal printer can print measurement result immediately. Can store 1000 patient datas. It is equipped with a standard RS232 serial port, via which the instrument transfers its saved data to the connected computer system.
