1Product Introduction

Huaxia Sci Tech has independently developed a fully automatic water quality permanganate index analyzer. The instrument adopts a three-axis intelligent robot structure, supporting positioning and movement in three degrees of freedom, and can achieve functions such as automatic sample preparation, automatic grasping, automatic positioning, and automatic analysis of samples.

The instrument testing section mainly includes four parts

(1)Sample preparation section

Adopting advanced automatic reagent feeding system, equipped with real-time monitoring throughout the process, the system can monitor and warn the remaining amount of reagents in real time;

（2） Dissolve part

Adopting water bath heating that meets national standards, the instrument is equipped with a high-precision automatic temperature control system to ensure temperature control accuracy while maintaining the lowest energy consumption;

（3） Testing section

Adopting mainstream biomimetic detection design, the light source is provided by highly reliable light-emitting diodes, and equipped with highly sensitive silicon photovoltaic cells as detectors;

（4） Software section

Upper computer software supportPCEnd and mobile end.

Huaxia Sci Tech Innovation Fully Automatic Water Quality Permanganate Index TesterCOD_Mn500, can be tested at once48A sample with high degree of automation, high work efficiency, low cost, time-saving, labor-saving, energy-saving and environmentally friendly characteristics.

2、 Compliant with standards:

GB/T11892Determination of permanganate index for water quality

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

3、 Application Fields

This instrument can be used for the detection of permanganate index in drinking water and surface water.

The permanganate index is an important indicator for water quality monitoring, which has a wide range of applications in environmental monitoring stations, hydrology, third-party testing, disease control, etc.

4、 Detection principle

Same as the national standardGB/T11892.

Add a known amount of potassium permanganate and sulfuric acid to the water sample and heat it in a boiling water bath30In minutes, potassium permanganate will oxidize certain organic and inorganic reducing substances in the sample. Then, excess sodium oxalate is added to reduce the remaining potassium permanganate, and excess sodium oxalate is dripped back with potassium permanganate standard solution. Finally, the permanganate index in the sample was calculated.
