product details

This product is the use of sealed catalytic digestion, and then colorimetric measurements. 

The instrument uses advanced , narrowband interference technology and microcomputer 

automatic processing of data , direct display of the sample COD (mg / L) and ammonia (mg / L) values. 

The instrument is widely used in environmental monitoring, wastewater treatment and universities, 

research institutes and other departments.

Feature 

●Analyzer separated with digestion device, without affecting the stability of the optical system. 

●Analyzer is cold light, narrowband interference optical system, good optical stability. 

●High temperature digestion PID automatic temperature control, high precision timing.

●Operation is simple and time-saving. digestion colorimetric no need to change tube. 

●Digestion temperature and time can be infinitely set to be used for other purposes. 

●Standard curves can be saved each 10 and 999 measured values, values is not lost when the power outage.

●LCD large-screen, easy and intuitive operation. 

●Has a factory recovery curve to restore accidentally deleted curve operation. 

●Has a print function: recording test print immediately or query records printed

●USB interface can be connected to a computer.
