Product Description
PCM200-CODcr China Wholesale PROBEST Chemical Oxygen Demand COD Online Automatic Water Quality Monitoring
PCM200-CODcr Chemical Oxygen Demand (CODcr) Water Quality Online Monitor
Working Principle
Product Features
Equipped with 10-way sapphire valve core, featuring high wear resistance, strong acid/alkali resistance, organic solvent resistance, long service life and high stability.
Adopts dedicated reference optical design; slight displacement of digestion cell and light pollution do not affect measurement accuracy.
Built‑in waste liquid separation function, realizing separate discharge of high-concentration reaction waste liquid and low-concentration cleaning waste liquid.
Supports dynamic dilution function, automatically adjusting dilution ratio according to on‑site range settings.
Integrated with complete quality control functions: standard addition recovery, blank test verification, prototype verification, zero check, span calibration and parallel sample testing.
Supports automatic, manual and remote start of quality control tasks.
Automatic fault diagnosis and alarm information upload & logging: component failure, out‑of‑range alarm, excessive limit alarm, reagent shortage alarm and more.
Overheating protection: heater cuts off power automatically when heating temperature is too high.
Abnormal reset & power recovery: the instrument automatically discharges residual reactants and restores to the original working state.
Power‑on alarm function generates prompt information when power is restored.
Log analysis, process recording, measurement data storage and alarm information archiving; hourly data recording with up to 5 years of storage capacity.
Support U-disk fast data export for convenient data management and report output.
Three-level management authority to ensure operation safety and data security.
Typical Applications
Online monitoring of municipal sewage outlet
Online monitoring of pollution source outlet
Online monitoring of industrial wastewater outlet
