Product Description

CODG-3000  Online COD Analyzer

BOQU has completely independent intellectual property rights  for CODG-3000 automatic online COD analyzer. it's user Potassium dichromate principle and totally auto-measurement and unattended for a long time.

Main features:
1)Unique design makes this product have lower failure rate, lower maintenance, lower reagent consumption and higher cost performance than similar products.
2)Select valve component: Select reagent sampling timing, flexible channels, wide function, minimum dead volume, easy maintenance and long life.
3)Micro-metering component: Accurate metering of reagents through visible photoelectric system, which overcomes the quantitative error caused by wear of peristaltic pump tube; at the same time, it realizes accurate quantification of trace reagents, each dose is only 1 ml, which greatly reduces the reagent usage.
4)Sample Injection component: peristaltic pump suction in negative pressure, there is always an air buffer between the reagent and the pump tube, avoiding the corrosion of the pump tube; at the same time, the reagent mixing is more compact and flexible.
5)Sealed digestion component: high temperature and high pressure digestion system, speeding up the reaction process, overcoming the corrosion of equipment by corrosive gas volatilization of open system
6)Reagent tube: imported modified PTFE transparent hose, the diameter of the tube is more than 1.5mm, reducing the probability of water sample clogging
