Which domestic brands are the best for COD detectors and turbidity meters? Those with a flow cell – can anyone recommend a few? Also, are there COD detectors and turbidity meters available with 24VDC power supply? I don’t want to use 220VAC power.
They are portable COD detectors and turbidimeters, both of which are available; for example, the HJ-200B portable COD detector and the WGZ-2B portable turbidimeter. They are rechargeable, which makes them convenient to use

The list of qualified online automatic water quality monitors from the National Environmental Monitoring Center is available at http://www.sinospectroscopy.org.cn/readnews.php?nid=41290. In theory, any device that is included in this environmental protection list is suitable for use. Among domestic products, Polyfocus Technology’s ones are widely used due to their high acceptance by the environmental protection authorities. The quality of domestic devices for measuring turbidity is relatively average; the several units I use from Beijing Tianjian are quite good
