KZCOD-2000X Online CODcr Chemical Oxygen Demand Analyzer
KZCOD-2000X online CODcr analyzer with high precision, low reagent consumption and industrial PLC control. Ideal for industrial wastewater and surface water quality monitoring.
# Upgrade your wastewater treatment process with the KZCOD-2000X Online COD Analyzer.
It is a high-performance system that brings you total automation, ultra accuracy in determining COD, cuts time and effort for lab testing, and increases product output while you maintain a clean environment and fulfill environmental standards all over the world. Whether you are an industrial plant or a community facility.
Core Advantages:
Compliance and Certification: The measurement technique complies with HJ 377-2019 standard. The instrument is also certified with CCEP environmental certification, complying with a regulatory requirement to meet standards.
- Precision and Anti-Interference: The system uses a sophisticated fluid flow path and smart data algorithms to minimize the effects of color and turbidity interference. A corrosion-resistant syringe pump with high precision ensures accurate dosing, stable CV value and a maintenance-free lifetime operation.
- Low Consumption & Easy Operation: Very few reagents used (1mL Reagent A, 1mL Reagent B, 2mL Reagent C) and the system generates almost no waste. The system incorporates waste liquid separation functionality that separates disposal of concentrated and clean reaction wastes of the system from the disposal of cleaning waste to avoid cross-contamination. Extended maintenance interval (once per month) provides excellent return on investment.
- Stability & Reliability: The PLC controller made for industrial environments boasts the greatest resistance to outside disruptions, lowest energy needs, and lowest power rating requirements to provide smooth and stable operation at all times.
- Flexible Measuring Range: An ultra-accurate syringe pump flow system is used for the dilution measurement process and enables the measurement range to be expanded without the use of extra instruments.
