Detection purpose:

It is suitable for the determination of drinking water, source water and surface water, with a determination range of 0.05-5.0 mg/L. For heavily polluted water, less water sampling can be carried out and the water can be measured after appropriate dilution.

According to the standard:

GB11892-89 "Determination of Permanganate Index of Water Quality"

GB/T5750.7 Comprehensive indicators of organic matter in drinking water standards

ISO8467-1986 "Determination of Permanganate Index of Water Quality"

New generation of permanganate index tester technical advantages:

Without an external sampler, it can also realize fully automatic sample weighing and automatic pipeline cleaning, and realize the whole process: automatic quantification - automatic reagent addition - automatic water bath digestion - automatic titration - automatic endpoint recognition - automatic calculation of results - data printing, automatic upload and other functions; two sets of high-precision injection pumps can realize simultaneous reagent addition, simultaneous titration, and simultaneous determination of titration endpoint without interfering with each other, doubling the work efficiency and greatly accelerating the detection speed, making your detection work simpler and easier:

1) 54 -position automatic sample tray, the samples to be tested do not need to be weighed, the equipment automatically quantifies, and can realize the function of unlimited cycle automatic sample injection, any number of samples can be automatically cycled for testing;

2) Fully automatic, high-speed and stable three-axis robot motion system, which can quickly transfer the samples from the test area to the digestion area and titration area;

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

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

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

6) The instrument adopts PLC control system, which makes the instrument more stable; the system automatically completes the entire experimental process and automatically outputs the experimental result data, which is convenient for experimental personnel to count;

7) 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 automatic water replenishment in case of water shortage to ensure that the sample to be tested is completely immersed in the boiling water bath.

8) A high-precision syringe pump is used for titration and sample addition, with a titration and sample addition accuracy of 5 ‰, reducing the impact of experimental titration errors on the results.

9) Automatically monitor the reagent liquid volume and display the reagent liquid level in real time.
