　working principle

The CN-201C COD and ammonia nitrogen analyzer can directly measure the concentration of COD and ammonia nitrogen in water samples. COD is a fast digestion optical method; Ammonia nitrogen is treated with Nessler's reagent
The law.

　Features

Utilizing imported high brightness and long-life cold light sources, the instrument has high stability and repeatability.

The digestion instrument and the host are separate and independent instruments, which does not affect the stability of the optical system.

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

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

The instrument adopts a 5-inch large screen color touch screen operation, with a user-friendly interface.

The ammonia nitrogen and COD analyzer has a one click recovery function.

Equipped with a USB interface, data can be transferred to a computer, and test records can be printed or queried.

The system has bilingual functionality and can switch between Chinese and English.

Type C can store 300 curves, while Type D can store 3500 curves; Type C can store 1000 records, while Type D can store 100000 records.

Optical system optimization upgrade (D-type), the system is more stable during measurement, with better accuracy and stability.
