◆ Others: Fault alarm, no loss of data in the case of power failure, and touch screen for display and command input; in the case of fault reset or power ON after power failure, the analyzer automatically discharges residual reagent inside and restores the working condition;
Measuring principle:
With the water sample oxidized by the oxidizing agent – ammonium persulfate, the nickel reacts with the indicator and produces a colored complex in the presence of alkaline environment and an indicator (dimethylglyoxime); the analyzer detects this color change and converts it into and outputs the total nickel. The colored complex produced amounts to the quantity of total nickel.
