PCM200-COD Colorimetric COD Online Analyzers Monitor for Wastewater Or Water

PCM200-CODmn Permanganate Index Water Quality Online Monitor

Features

1. Acidic potassium permanganate oxidation titration method. 

2. The electrode is used to determine the end point of the titration, which is not disturbed by the color and turbidity of the water sample, and the measurement result is more accurate. 

3. Ten-port valve with sapphire core, high wear resistance, strong acid and alkali resistance, organic solvent resistance, strong service life and high stability. 

4. It has the function of separating waste liquid, and realizes the storage of high-concentration reaction waste liquid and low-concentration cleaning waste liquid. 

5. With automatic dilution function, it can automatically adjust the range file according to the actual water quality on site.

6. With three-level management authority.

7. It has built-in quality control functions such as standard recovery, zero-point verification, standard sample verification, parallel sample test, etc.With automatic fault diagnosis and abnormal information uploading and recording functions, such as parts failure, over-range alarm, over-standard alarm, lack of reagent alarm and other information. 

8. After abnormal reset and power failure, the instrument automatically discharges the residual reactants in the instrument and automatically restores to the original working state. With power-on alarm function, the instrument will generate alarm information when power is turned on again after power-off.With overheating protection. 

9. It has the function of analyzing instrument process log, measurement data record and alarm information storage

Typical Application

On-line monitoring of permanganate index of drinking water and surface water.
