PCM200-COD Colorimetric COD Permanganate Index Water Quality Analyzers Monitor for Wastewater Or Water | PROBEST
Product Description
Meta Description
PCM200-CODmn Permanganate Index Water Quality Online Monitor
Overview
Measurement Principle
The instrument adopts the acidic potassium permanganate oxidation titration method. The titration end point is determined by electrode, which is not disturbed by water sample color or turbidity, ensuring stable and accurate measurement results.
Key Features
Acidic potassium permanganate oxidation titration method, stable and standard detection principle.
Electrode-controlled titration end point, not affected by water color and turbidity, with higher accuracy.
Equipped with ten-port valve with sapphire core, high wear resistance, strong acid & alkali resistance, organic solvent resistance, long service life and high stability.
Separate waste liquid collection function, realizes classified storage of high-concentration reaction waste liquid and low-concentration cleaning waste liquid.
Automatic dilution function, can automatically adjust the range according to actual on-site water quality.
Three-level management authority for safe operation and data management.
Built-in comprehensive quality control functions: standard recovery, zero-point verification, standard sample verification, parallel sample test; supports automatic fault diagnosis, over-range alarm, over-standard alarm, reagent shortage alarm, data upload and record.
Automatic recovery after power failure / abnormal reset: automatically discharges residual reactants and restores working status; supports power-on alarm and overheating protection.
Stores process log, measurement data and alarm information, supporting traceable data management.
Typical Applications
On-line monitoring of permanganate index in drinking water
On-line monitoring of permanganate index in surface water
Environmental water quality monitoring & regulatory compliance
