It has data storage function and data power-off protection function, making it convenient to query historical measurement data and prevent data loss.

It has the function of curve coverage interference to prevent accidental operation of covering curves.

COD analyzer manufacturers combine colorimetric methods with computer technology, replacing traditional visual colorimetric methods with microcomputer optoelectronic colorimetric detection principles, eliminating human errors, and greatly improving measurement resolution. This product has the characteristics of automatic PID temperature control, dual LCD display, AC/DC dual-use, automatic zero adjustment, concentration direct reading, curve storage, automatic printing, etc. The instrument is easy to operate, human-machine interactive operation, and users can apply this product without complex knowledge.

The COD analyzer manufacturer's instrument for measuring COD has the following advantages compared to standard chemical methods:

1. Time saving operation. The potassium dichromate method takes 30 minutes to analyze the entire process of a sample, the potassium permanganate index method takes 40 minutes to analyze the entire process, and the general standard chemical method takes about half a day to determine the entire process.

2. Save reagents.

3. Iron sulfate does not require daily calibration. Because the titration of ferrous ions is produced by electrolysis on the cathode, it can be used for electrolysis at any time, eliminating the need for reagent calibration.

4. For water bodies with high chloride content (generally above 60mg/L), only silver nitrate is needed to eliminate interference. In the standard chromium method, for water bodies with chloride content higher than 30mg/L, mercuric sulfate is required to eliminate interference, thereby introducing secondary pollution.

5. Both high and low levels can be measured. The instrument can directly measure water bodies with COD values below 800mg/L, and water bodies with COD values above 800mg/L can be diluted for measurement. When the COD value of the water sample is below 2mg/L to 3mg/L, it can still be measured. The sensitivity of the instrument is 0.3mg/L, which is far beyond the standard method.

6. From the perspective of the instrument itself, the titration endpoint is automatically controlled. This is because the instrument uses a computer to determine the endpoint, and the results are directly displayed, which is accurate and reliable.

7. The instrument can directly display the COD value of the water sample (in mg/L), eliminating the need for complicated calculations. This instrument is suitable for environmental monitoring stations in various provinces, cities, and counties, sewage treatment plants in factories and mines, as well as teaching and research institutions.
