I. Performance characteristics
★1. automatic detection process: dilution, alkali addition and distillation are done fully automatically;
★2. alkali pump anti-crystallization technology, completely eliminate the problem of alkali pump crystallization, maximize the reliability of the instrument;
★3. sample dilution and alkali addition method, according to the different samples, can be set according to the user's needs, so as to accurately carry out batch, time, quantitative dilution and alkali addition, to prevent the occurrence of sample boil-off phenomenon to the maximum extent, to improve the measurement accuracy;
★4. the steam flow rate can be adjusted between 0-100% according to the user's needs to better achieve the distillation effect and ensure the accuracy of the experiment;
★5. all solutions using pump suction, safe and reliable;
★6. built-in multiple safety protection: digestion tube in position detection, safety gate, condensate detection, steam generator overheating, overpressure protection, liquid level detection and other multiple intelligent protection to ensure the safety of the instrument and the operator;
7. all pipelines and action elements are made of anti-corrosion materials and finely crafted;
8. the use of large touch screen LCD screen, with Windows-like operating interface, simple and easy to use;
★9. 500 sets of distillation solutions can be stored, effectively simplifying the user's operation.
★10. Waste liquid evacuation function of the digestion tube, safe and worry-free
