Performance characteristics of ST-L1200 industrial COD online analyzer

1. Adopting peristaltic pump technology, with constant rotational speed, stable and accurate injection; Equipped with ultra wear-resistant peristaltic pump tubing, with a long service life;

2. Adopting a constant temperature module to ensure the working environment of the electrodes is not affected by external factors;

3. Dual filtration setting, suitable for water with high suspended solids, impurities, and floating objects. The precision pretreatment system has self-cleaning, backwashing, and precision filtration functions, ensuring good representativeness of the sample while avoiding blockage of the pipeline by large suspended particles, and can be separated from the upper host;

4. Adopting a nine way valve sampling system, it has strong corrosion resistance, long service life, and effectively avoids the compression aging of traditional pipelines;

5. Adopting a dedicated power supply system for the power system, preventing electromagnetic interference, ensuring unstable power grids, and greatly reducing after-sales costs;

5. 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 1.5 millimeters and no leakage;

6. Can store 20000 measurement data, automatically overwrite early data when fully stored, and data will not be lost in case of power failure;

7. When powered off, the instrument automatically stops working and stands by, and automatically resets when powered on;

8. Regularly clean the pipeline (adjustable time), clean the pipeline after each sample (adjustable switch), saving time and effort:

9. Equipped with an original 7-inch TFT 70000 color true color touch screen, with three interface operating languages of Chinese, English, and Chinese, which can be interchanged at any time, and can be upgraded to Uyghur, Tibetan, and other languages;

10. Optional high-quality micro industrial printer (with adjustable switch);

11. Timed sample making (adjustable time), supports remote start of sample making, ensures networking:

12. Equipped with RS232 interface (convertible to RS485 interface, communication protocol publicly available), meeting the requirements of digital networking;

13. Equipped with 4-20mA analog output (adjustable range for 20mA), it can be easily connected to the internet.
