Product Introduction:

The TGH-SCODMn potassium permanganate index water quality online automatic monitoring instrument adopts the principle of potassium permanganate oxidation titration for detection. The pre treated water sample is oxidized and digested by potassium permanganate under constant temperature conditions, and then reduced by adding excess sodium oxalate solution. The excess reducing agent is titrated with potassium permanganate solution, and the titration endpoint is determined by absorbance or oxidation-reduction potential. The potassium permanganate index value is calculated by the volume of potassium permanganate dripped back. The measurement method used by the instrument meets the requirements of the "Technical Requirements for Permanganate Index Water Quality Automatic Analyzer" (HJ/T1002003) standard.

Product features:

1. Selecting valve components, selecting reagent sampling timing, flexible and diverse channels, with advantages such as minimum volume, easy maintenance, and long lifespan.

2. The visual photoelectric system achieves precise measurement of reagents through the visual photoelectric system, overcoming quantitative errors caused by wear of peristaltic pump tubes.

3. Micro metering components have precise quantification of trace reagents, reducing the amount of reagents used.

4. Sample injection component, peristaltic pump negative pressure suction, air buffer zone set between reagent and pump tube to avoid corrosion of pump tube; At the same time, it makes the mixing of reagents more concise and flexible.

5. Multiple sets of multi-channel discharge valves enable rapid switching of liquid inlet, while also allowing for real-time verification of various standard solutions without the need for manual intervention.

6. It has functions such as automatic range switching, automatic standard sample verification, and waste liquid separation.

7. Reagent tube: Imported modified PTFE transparent hose with a diameter greater than 1.5mm is used to reduce the probability of particle blockage in water samples.
