SIA-3000 series COD analyzer applies advanced sequence injection platform, based on the principle of oxidized by potassium dichromate-photometry to realize reliable and accurate COD monitoring results.
Product features
It adopts the sequence injection platform which is advanced in the world.
Innovative structure of liquid storage ring, the sample or reagent never touches directly the injector, for avoiding the abrasion and corrosion of injection flow path.
The flow path of valve head adopts the laser micro-machining technology, which can control precisely the dimension and position of notch groove, ensure that the flow path will be with no dead volume when the valve position shifts, thus guarantee that there will be no residual reagent.
Application area
Municipal wastewater
Industrial sewage
Industrial process water supply
