Working principle

COD、 The ammonia nitrogen and total phosphorus analyzer can directly measure the concentrations of COD, ammonia nitrogen, and total phosphorus in water samples. COD is a fast digestion optical method; Ammonia nitrogen adopts the Nessler's reagent method; Total phosphorus is obtained using the phosphomolybdic blue method.

Product Features

The multi parameter water quality detector utilizes imported high brightness and long-life cold light sources, with high instrument 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.

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.

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

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

The instrument has a one click recovery function.

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