Features



1. Using imported high brightness, long-life cold light source and high stability narrow-band interference optical system, the instrument has high stability and repeatability.

2.  Separate independent digester and main engine, which do not affect the stability of the optical system.

3. The temperature of digester is controlled and timed automatically by PID with high precision.

4. Free setting of digestion temperature and time for other purposes.

5. The same digestion colorimetric tube is used for digestion and colorimetry, which has high strength and hardness and can be used repeatedly.

6. LCD large screen display, long life and low failure rate, Chinese menu display for operation.

7. 20 standard curves and 400 measurements of COD, ammonia nitrogen, total phosphorus and total nitrogen can be saved respectively, data will not lose even when power is cut off.

8. Printing function: the test record can be printed immediately and the query record also can be printed.

9. With USB interface data upload function, the data record saved in the instrument can be uploaded to the computer for saving or editing and printing.
