Product features: (Our company has developed 25, 29, 48, 54 full-automatic permanganate index testers, please contact 053186970887 for more product information)
The sample does not need to be quantified, the system automatically injects samples, adds reagents, digests in a water bath, titrates at a constant temperature, judges the end point, calculates the results, and uploads or prints with one button.
It can support the acid method and alkaline method to detect the permanganate index in water at the same time, one-click selection! For high concentration, the dilution ratio can be selected independently for automatic quantification, and the follow-up detection work can be completed automatically.
Jinan Shengtai ST1900 Full-automatic Permanganate Index Tester Full Experimental Demonstration Video:
Detection purpose:
It is suitable for the determination of drinking water, source water and surface water. The determination range is 0.05-5.0mg/L. For heavily polluted water, less water samples can be taken and measured after proper dilution.
According to the standard:
GB11892-89 "Determination of Water Quality Permanganate Index"
GB/T5750.7 "Comprehensive indicators of organic matter in drinking water standards"
ISO8467-1986 "Determination of Water Quality Permanganate Index"
Technical advantages:
Originally configured with 29 high-intelligence automatic sample trays, no need to weigh samples, automatic quantification-automatic reagent addition-automatic water bath digestion-automatic titration-end point automatic recognition-automatic calculation of results-data printing, automatic uploading and other functions. In the whole process, you only need to manually put the sample into the sample tray, and the other work is automatically completed by the instrument. The test results can be uploaded as you like with one click, and your work is simpler and easier:
1) 29-position automatic sampling tray, the sample to be tested does not need to be weighed, and the equipment automatically transfers the sample quantitatively to the sample area. The injector has a pipeline cleaning function without cross-contamination.
2) High-concentration samples can be diluted automatically, and all the work can be completed only by the experimenter selecting the dilution ratio.
3) The fully automatic three-axis robot motion system can quickly realize the transfer of the sample to be tested from the area to be tested to the digestion area and titration area;
4) The sample is automatically added with sulfuric acid and potassium permanganate solution in the reagent addition area. If the sample has been acidified, click "cancel acid addition" in the system operation area;
5) Automatic water bath digestion, after the digestion, in a constant temperature environment (60-80 degrees) back drop excess sodium oxalate with potassium permanganate;
6) Automatic determination of the titration end point, using advanced visual sensing technology higher than the human eye, automatically determines the titration end point through color changes, with higher accuracy and faster response speed;
7) The instrument adopts a PLC control system to make the instrument more stable; the system automatically completes the entire experimental process and automatically outputs the experimental result data, which is convenient for the statistics of the experimenters;
8) According to the national standard, the heating method of boiling water bath is adopted to make the sample be heated more evenly. At the same time, it has the function of automatic water replenishment in case of water shortage, so as to ensure that the sample to be tested is completely immersed in the boiling water bath.
9) High-precision syringe pumps are used for titration and sample addition, and the titration and sample addition accuracy reaches 3 ‰, which reduces the influence of experimental titration errors on the results.
10) Automatically realize the safety monitoring of the reagent liquid volume, and display the reagent liquid level in real time.
