KD-2030 COD ammonia nitrogen analyzer

1、 Instrument features

1. Utilizing imported high brightness, long-life cold light sources, as well as highly stable narrowband interferometric optical systems, to achieve extremely high stability and repeatability of the instrument.

2. The digestion instrument and the host are independent instruments that do not affect the stability of the optical system.

3. The digestion instrument has PID automatic temperature control and timing, with high accuracy.

4. The digestion temperature and time can be infinitely set for other purposes.

5. Use the same digestion colorimetric tube for digestion and colorimetry, which has high strength and hardness and can be reused multiple times.

6. It can store 100 standard curves and 999 measured values for COD and ammonia nitrogen, without losing them when powered off.

7. It has printing function: it can print the test records immediately or query the records for printing.

8. It has a USB interface data upload function, which can upload the data records stored in the instrument to the computer for saving or editing and printing.

9. LCD large screen display, long lifespan and low failure rate, with Chinese menu display for operation.
