Chemical Oxygen Demand COD Analyzer
Features:
1. The analyzer is separated from the digestion device and does not affect the stability of the optical system.
2. The measuring instrument is a cold light source and a narrow-band interference optical system with good optical stability.
3. The measuring instrument and the digestion instrument are both color touch screens, with friendly operation interface and Chinese and English display.
4. Simple and time-saving operation. There is no need to change the color of the colorimetric.
5. The instrument has a one-key recovery function to prevent accidental loss of curves and data.
6. The instrument comes with a calibration function, which can be self-calibrated during operation, which can effectively eliminate the drift error caused by long-term use.
7. The digestion instrument has multi-point error-free calibration, which realizes the zero error measurement of the set point, completely eliminating the error caused by the nonlinearity of the common decomposer on the market due to the temperature sensor.
8. The digestion instrument has a timed reminder, which can set the automatic shutdown function after digestion. The instrument has secondary protection function. When the temperature of the digestion device exceeds 200 degrees, the instrument will cut off the power supply to ensure the safety of the digestion process.
9. 300 standard curves and 1000 measured values can be stored, and power is not lost.
10. For the curve query, in addition to the query curve equation, the standard value of each standard substance and the corresponding absorbance as well as the calibration time and the calibration personnel number can be queried to fully reproduce the state of the calibration.
11. With printing function: Single or page printing can be performed on the records of the test.
12.USB interface, can be connected to the computer.
