2TW-56 series online environmental protection instrumentBasic Principles

The components to be tested in the water sample react with reagents A, B, C, etc. to produce substances of different colors. The analyzer detects this color change and calculates the corresponding components to be tested within the range of Beer's law.

3. Characteristics

1) Large screen LCD and touch screen display, intuitive and easy to operate;

2) The quantitative system adopts American photoelectric quantitative technology, which provides more precise and accurate sampling;

3) Having dual filtering function, it can adapt to water with high suspended solids, impurities, and floating objects;

4) Adopting Masterflex peristaltic pump technology from the United States;

5) The pump tube adopts * ultra wear-resistant pump tube;

6) All pipelines are made of imported 3-fluorine and 4-fluoro materials that are resistant to high temperatures and corrosion, with an inner diameter of 1.5mm and no leakage;

7) The sampling system adopts Germany's nine way valve technology to eliminate the pressure and aging of pipelines;

8) Scheduled pipeline cleaning (adjustable time), cleaning the pipeline each time (adjustable switch);

9) Store 20000 records for easy retrieval of historical data;

10) Equipped with analog and digital interfaces for easy data transmission;
