JX-820 multi-parameter water quality analyzer (COD / ammonia nitrogen /  total nitrogen)

Application field

1. COD, ammonia nitrogen (measured by a separate machine).

2. Can be used for the analysis of COD, ammonia nitrogen and total phosphorus.

3. Support DIS-16 type (or optional DIS-25/1A/36) digestion instrument.

4. With printing and USB data upload.

5. For wastewater testing.

Main feature

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. The temperature of the digestion instrument is automatically controlled by temperature and timing, and the precision is high.

3. The digestion temperature and time can be set steplessly for other purposes.

4. Digestion and colorimetry use the same digestion colorimetric tube, which has high strength and hardness and can be reused many times.

5. With print function: the test record can be printed immediately or the record print can be queried.

6. With USB interface data upload function, the data record stored by the instrument can be uploaded to the computer for saving or editing and printing.

7.LCD large-screen LCD display, long life and low failure rate, operating Chinese menu display.
