Related Product Recommendations
How does this COD analyzer ensure accurate results in high-chloride wastewater?
The analyzer resists interference from chloride ions up to 1000 mg/L (standard) or 4000 mg/L (optional), reducing false readings and eliminating the need for extensive sample pretreatment. Engineers can rely on stable and repeatable COD data in challenging industrial wastewater conditions.
Can this analyzer be used for rapid field measurements as well as laboratory analysis?
Yes. With its compact 1.0 kg design and digital display, the instrument is easily portable for field inspections, while providing laboratory-grade reproducibility (≤±3%). This flexibility supports both compliance monitoring and on-site process optimization.
How fast can operators obtain COD results and why is this advantageous?
Using the rapid catalytic (chromium) method, the analyzer delivers results in 15 minutes. For process control or environmental monitoring, this enables immediate corrective actions without waiting for centralized lab results, reducing downtime and operational risk.
What makes this COD analyzer suitable for industrial procurement and lifecycle cost management?
The analyzer is low-power (3W), maintenance-free, and robust against environmental conditions (5–40°C, RH <85%). Minimal consumables and high reproducibility reduce total cost of ownership while ensuring reliable performance across multiple sites or plants.
How does the analyzer handle COD levels above 800 mg/L?
For high-COD samples, a dilution measurement method is used, allowing operators to extend the detection range safely. This ensures accurate readings in heavily contaminated wastewater, common in chemical, food, or textile industries.
What features simplify adoption for engineering teams and procurement decision-makers?
Digital display and cuvette-based colorimetry for intuitive use
Compact and lightweight design for field portability
Standard AC 220V power ensures compatibility in industrial and laboratory settings
These features reduce training time, simplify inventory planning, and allow immediate integration into existing water quality monitoring programs.
