n Main features
u Using the redox potential end point determination method, not affected by the chromaticity and turbidity of the water sample, and the measurement result is more accurate and true;
u Accurate sampling of syringe pump, the water sample and reagent take amount is more stable and accurate;
u Accept remote control commands and has quality control functions such as zero check, standard check, parallel sample test, and standard recovery;
u With the process log record function of the analysis instrument, the data calculation is recorded once every hour, which can be stored for 3 years, and the data can be quickly downloaded by the U disk;
u It has automatic fault diagnosis function, with abnormal information record and upload function, such as component fault, over-range alarm, over-standard alarm, lack of reagent alarm and other information;
u Have three levels of management authority;
u After abnormal reset and incoming call after power failure, the instrument automatically discharges the residual reactants in the instrument and automatically returns to the initial working state. With power-on alarm function, the instrument will generate alarm information when power is turned back on after power off;
u With overheat protection: the heating temperature is too high and the heater is automatically powered off;
u With 7-inch touch screen and simple operation interface, users are easy to learn, easy to operate and easy to maintain.
