Next-Generation Permanganate Index Determination Instrument Technical Advantages:

No external sampler required, one sample can achieve fully automatic sample weighing, pipeline automatic cleaning, and full-process automation: automatic quantification - automatic reagent addition - automatic water bath digestion - automatic titration - automatic endpoint recognition - automatic result calculation - data printing, automatic upload, etc.; two sets of high-precision injection pumps can achieve simultaneous reagent addition, simultaneous titration, simultaneous endpoint judgment, without interference, doubling work efficiency, greatly accelerating detection speed, making your detection work simpler and more relaxed:

1)54-position automatic sample tray, no need to weigh samples to be tested, equipment automatically quantifies, and can achieve unlimited cycle automatic sampling function, any number of samples can be automatically cyclically detected;

2)Fully automatic high-speed stable three-axis robotic motion system, quickly realizing the transfer of samples to be tested from the waiting area to the digestion area and titration area;

3) Samples automatically add sulfuric acid and potassium permanganate solution in the reagent addition area. If the sample has been acidified, you can click "Cancel Acidification" in the system operation area;

4) Automatic water bath digestion, after digestion, in a constant temperature environment (60-80 degrees), use potassium permanganate to back-titrate excess sodium oxalate;

5) Automatic endpoint determination, using advanced visual sensing technology superior to human eyes, automatically determining the titration endpoint through color changes;

6) The instrument adopts a PLC control system, making the instrument more stable; the system automatically completes the entire experimental process, automatically outputs experimental result data, facilitating statistical analysis by experimenters;

7) According to national standards, boiling water bath heating is adopted, making samples more evenly heated, while having automatic water replenishment function to ensure samples to be tested are completely immersed in boiling water bath;

8) High-precision injection pumps are used for titration and sample addition, with titration and sample addition accuracy reaching 5‰, reducing the impact of experimental titration errors on results.

9) Automatic reagent liquid level safety monitoring, real-time display of reagent liquid level. 

10) Barometric self-adaptation, can automatically detect local atmospheric pressure, temperature and humidity changes, real-time adjustment of heating temperature and time parameters.
