QCOD-3M_COD Rapid Tester Introduction: The QCOD-3M COD meter utilizes advanced cold light sources, narrow-band interference technology, and microcomputer-based automatic data processing. It employs sealed catalytic digestion followed by colorimetric measurement. It is suitable for environmental monitoring, wastewater treatment, as well as use in universities, colleges, and research institutions Features: The measuring instrument and digestion instrument are separated, which does not affect the stability of the optical system. 2. The measuring instrument features a cold light source and a narrow-band interference optical system, ensuring excellent optical stability. 3. Both the measuring instrument and the digestion instrument feature color touch screens with a user-friendly interface that displays in both Chinese and English. The operation is simple and time-saving. There is no need to change tubes for digestion colorimetry. 4. The digestion instrument features multi-point error-free calibration, achieving zero-error measurement at set points, completely eliminating the errors caused by nonlinear temperature sensors commonly found in digestion instruments on the market. 5. The digestion instrument features a timed reminder and can be programmed to automatically shut down after digestion. The instrument also boasts a secondary protection function. When the temperature of the digestion instrument exceeds 200 degrees, it will automatically cut off the power supply to ensure the safety of the digestion process. 6. It can store up to 100 standard curves and 1000 measured values, and the data will not be lost in case of power failure. 7. Curve queries are available. In addition to querying the curve equation, users can also inquire about the standard values of each standard substance during calibration, along with their corresponding absorbance, calibration time, and the number of the calibration personnel, fully reproducing the state during calibration. 8. Printing function: It allows for single item or page printing of test records. 9. USB interface, compatible with computers. 10. The instrument features a one-click recovery function to prevent accidental loss of curves and data. 11. The instrument comes with a built-in calibration function, which allows for self-calibration during operation, effectively eliminating drift errors caused by long-term use.
