Brand: Erun
Name: Benchtop Water COD Analyser
Model: ERUN-ST3-J5
COD (sealed catalytic digestion)
ERUN-ST3-J5 Benchtop COD Analyser, which is produced by Erun, uses sealed catalytic digestion followed by colourimetric measurement.The instrument adopts advanced cold light source, narrow band interference technology and microcomputer automatic data processing, directly displaying the COD (mg/L) value of the sample.The instrument is widely used in environmental monitoring, sewage treatment, and colleges and universities, scientific research units and other departments.
