COD-2M type COD Analyzer
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.
