Product features: (Our company has developed 25, 29, 48, 54-digit automatic permanganate index testers. For more product information, please contact 053186970887)
The sample does not need to be quantified. The system automatically introduces samples, automatically adds reagents, automatic water bath digestion, automatic constant temperature titration, automatic end point judgment, automatic calculation results, and one-click upload or print.
It can simultaneously support the acid method and the alkaline method to detect the permanganate index in the water, one-click selection! The high concentration can choose the dilution ratio and quantify automatically, and automatically complete the follow-up detection work.
The whole experiment demonstration video of Jinan Shengtai ST108M high-precision permanganate index tester:
It is suitable for the determination of drinking water, source water and surface water, and the measurement range is 0.05-5.0mg/L. For water with heavy pollution, less water samples can be taken and measured after proper dilution.
According to the standard:
GB11892-89 "Water Quality Determination of Permanganate Index"
GB/T5750.7 "Comprehensive Indexes of Organic Compounds in Drinking Water Standards"
ISO8467-1986 "Water Quality Determination of Permanganate Index"
Originally equipped with 28 high-intelligence automatic sampling tray, the sample does not need to be weighed, automatic quantification-automatic addition of reagents-automatic water bath digestion-automatic titration-automatic end point recognition-automatic calculation results-data printing, automatic upload and other functions. The whole process only needs to manually put the sample into the sample tray, and other tasks are automatically completed by the instrument, and the test results can be uploaded as you like with one key. Your work is simpler and easier:
1) 28-position automatic sample injection tray, the sample to be tested does not need to be weighed, and the device automatically transfers the sample to the sample area quantitatively. The sampler has a pipeline cleaning function and will not cause cross-contamination.
2) High-concentration samples can be automatically diluted, and all the work can be completed only by selecting the dilution ratio by the experimenter.
3) Fully automatic three-axis robot motion system, which quickly realizes the transfer of the sample to be tested from the test area to the digestion area and the titration area;
4) The sample automatically adds sulfuric acid and potassium permanganate solution to the reagent addition area. If the sample has been acid added, click "Cancel acid addition" in the system operation area;
5) Automatic water bath digestion. After the digestion, the excess sodium oxalate is dripped back with potassium permanganate in a constant temperature environment (60-80 degrees);
6) The titration end point is automatically determined, using advanced visual sensing technology higher than the human eye, and the titration end point is automatically determined through color changes, with higher accuracy and faster reaction speed;
7) The instrument adopts a PLC control system to make the instrument more stable; the system automatically completes the entire experiment process and automatically outputs the experimental result data, which is convenient for the statistics of the experimenter;
8) According to the national standard, the boiling water bath heating method is adopted to make the sample heated more evenly. At the same time, it has the function of automatically replenishing water when the water is lacking to ensure that the sample to be tested is completely immersed in the boiling water bath.
9) The high-precision syringe pump is used for titration and sample addition, and the accuracy of titration and sample addition can reach 3 ‰, which reduces the influence of experimental titration errors on the results.
10) Automatically realize the safety monitoring of reagent liquid volume and display the reagent liquid level in real time.?
