2. The analyzer is a cold light source, narrow-band interference optical system, with good optical stability. 3. The digester adopts a 3.5-inch color touch screen with a resolution of 320x240, both Chinese and English display. Simple and time-saving operation. The digestion colorimetry does not need to be changed. 4. With the function of multi-point error free calibration, zero error measurement of set point can be realized, and the error caused by nonlinearity of temperature sensor in common digesters in the market can be completely eliminated. 5. The digester has the function of timing reminder, automatic shutdown after digestion. And the instrument has secondary protection function. When the temperature of digester exceeds 200 ℃, it will cut off the power supply by itself to ensure the safety of digestion process |
6. 20 standard curves and 199 measurements of COD and ammonia nitrogen can be saved and data will not lose even when power is cut off. 7. Large screen LCD Chinese display, convenient and intuitive operation. 8. The main engine shell is made of molded ABS material with good corrosion resistance. |
1. The analyzer is separated from the digester, which does not affect the
stability of the optical system.
