QCOD-3M-COD Analyzer

[Product Overview]

The QCOD-3M COD water quality measurement instruments, developed and produced by Shenchanghong, use advanced cold light source, narrow-band interference technology and microcomputer to automatically process data. The instrument first digests the sample with sealed catalyst, and then measure them by colorimetric method.

 

 

[Application Area]

Widely used in drinking water, groundwater, surface water, municipal sewage, industrial sewage, environmental monitoring, colleges and universities, scientific research institutions and other fields water measurements.
