Characteristic of COD Analyzer PCOD-3M:

  • Separation of Analyzer and Digester

The separation ensures that the analyzer doesn't impact the stability of the optical system in the digester. This design choice enhances the overall performance and accuracy of the analysis.

  • Optical System

The analyzer utilizes a cold light source and a narrow-band interference optical system, providing excellent optical stability. This choice of technology contributes to reliable and consistent results in COD analysis.

  • User-Friendly Interface

Both the analyzer and digester feature a color touch screen with a user-friendly interface. This makes the operation intuitive and accessible for users.

  • Operation Efficiency

The digestion colorimetry process does not require changes, simplifying and saving time in the operation. This feature streamlines the analysis process for more efficient water quality testing.

  • Multi-Point Error-Free Calibration

The digester employs multi-point error-free calibration, ensuring zero error measurements at set points. This eliminates errors that might arise from the nonlinearity of temperature sensors in common digesters, contributing to more accurate results.

  • Safety Features

The digester includes a timing reminder function and an automatic shutdown after digestion. Moreover, there is a secondary protection feature that cuts off power if the digester's temperature exceeds 200 ℃, ensuring the safety of the digestion process.

  • Data Storage and Retrieval

The analyzer can store up to 300 standard curves and 1000 measurements, with data retention even in the event of a power outage. The ability to inquire about curve details, standard substance values, absorbance, calibration information, and calibration state enhances traceability and reproducibility.

  • Printing Function

The analyzer allows for the printing of single or multiple page results, facilitating documentation and reporting of analysis outcomes.

  • Connectivity

Equipped with a USB interface, the instrument can be connected to a computer for data transfer and further analysis.

  • One-Key Recovery

The instrument features a one-key recovery function, preventing accidental loss of curve and data. This ensures data integrity and reduces the risk of errors.

  • Self-Calibration Function

The instrument has a self-calibration function, allowing it to recalibrate during operation. This feature helps eliminate drift errors that may occur over prolonged use, maintaining measurement accuracy.

These characteristics collectively make the Lab Fast COD Analyzer a comprehensive and efficient tool for water quality treatment analysis.
