CN-201 COD-Ammonia Nitrogen Analyzer

Principle:

CN-201 Type COD-Ammonia Nitrogen Analyzer can directly measure COD and Ammonia Nitrogen values in samples. The determination method of COD is sealed catalytic digestion and color comparison; The determination method of Ammonia Nitrogen is Mrs. Pay Reagent. This analyzer uses cold light source and narrow bandwidth wavelength and directly displays the COD and Ammonia Nitrogen values. It is widely used in environmental monitoring department, wastewater treatment, universities and research institutes, etc.

Features:

1. Cold and Monochromatic light source, excellent optical stability and cannot be interfered by all kinds of light.

2. PID automatic temperature control and high precision.

3. Two-line LCD, easy to operate.

4. Digester and colorimeter (including main unit) are separated, avoid temperature interfere with the optical part.
5. High efficiency, 20/16 water samples can be digested each time and only needs 20 minutes.

6. 8/10 working curves in memory (may set by user), and store 255/199 COD records and 100/199 Ammonia Nitrogen records with time label.

7. Historical data and curve can permanently keep in the analyzer, data protection when power failure.
