CODCr_Water Quality Analysis Instruments

CODCr water quality analysis instruments are laboratory and field-portable devices measuring chemical oxygen demand (dichromate method) quantifying organic contamination levels in water samples, enabling environmental monitoring, wastewater treatment verification, and drinking water quality assessment. The CODCr measurement provides objective characterisation of water quality compliance with environmental discharge standards and safety guidelines.

Premium CODCr instruments employ dichromate oxidation methodology where potassium dichromate oxidises organic compounds at elevated temperature (150°C) in acidic conditions, with measurement of unreacted dichromate through titration or spectrophotometry quantifying original organic concentration. Measurement range typically spans 5–2,000 mg/litre enabling assessment across untreated wastewater through pristine surface waters. Analysis time typically spans 30–60 minutes per sample enabling multiple daily measurements.

Portable field instruments enable on-site water quality assessment at sampling locations eliminating transport delays and sample degradation during laboratory transit. Fixed laboratory installations enable high-throughput sample processing across multiple daily samples supporting continuous monitoring programmes.

Regulatory compliance in Pakistan requires adherence to Pakistan Environmental Protection Agency (PEPA) surface water quality standards specifying maximum CODCr concentration dependent on water body classification — pristine waters <10 mg/L, treated effluent discharge typically <200 mg/L. Objective CODCr measurement provides compliance documentation.

Integration with Geographic Information Systems (GIS) enables mapping of organic contamination spatial distribution across watershed regions identifying pollution source locations enabling remediation prioritisation.

In Pakistan, CODCr instruments support environmental protection agency monitoring and municipal wastewater treatment.
