COD-500 Intelligent COD Rapid AnalyzerInstrument characteristics

1. The separation of the measuring instrument and the digestion instrument does not affect the stability of the optical system.
2. The measuring instrument is a cold light source and narrowband interferometric optical system with good optical stability.
3. Both the measuring instrument and the digestion instrument are color touch screens with a user-friendly interface and display in both Chinese and English.
4. Simple and time-saving operation. Dissolving colorimetric does not require changing the tube.
5. The instrument has a one click recovery function to prevent accidental loss of curves and data.
6. The instrument comes with a calibration function that allows for self calibration during operation, effectively eliminating drift errors caused by long-term use.
7. The digestion instrument has multi-point calibration to achieve measurement of the set point,*Eliminating the errors caused by the nonlinearity of temperature sensors in common digesters on the market.
8. DigesterEquipped with timed reminders, automatic shutdown function after digestion can be set, and the instrument has secondary protection function. When the temperature of the digestion instrument exceeds200When the temperature is low, the instrument will cut off the power supply by itself to ensure the safety of the digestion process.
9. Can store standard curves300Article and1000The measured value is not lost when the power is turned off.
10. Can query curves, in addition to querying curve equations, it can also query the standard value and corresponding absorbance of each standard substance during calibration, as well as the calibration time and calibration personnel number, * reproducing the state during calibration
11. Printing function: It can print single items or pages of test records.
12. USBInterface, capable of connecting to a computer.
