Chlorine residual meter
Thread Content
Does anyone know where I can buy a residual chlorine meter? Be good friends, okay?
There should be products used by peers on chemical industry forums; you’d better search on Baidu. There are many manufacturers selling such items, so gather some information and study it carefully
We use Hana from Italy; it works well, but one has to use their specialized reagents.
Chlorine residual analyzers are divided into two categories. One category involves the use of chemical reagents, which are further divided into two subcategories: chemical colorimetry and chemical reagent conversion-electrochemical methods. Another category is electrochemical methods, which use polarographic electrodes to measure residual chlorine. In terms of instrument design, there are also two types: one for measuring total chlorine and the other for measuring active chlorine. These manufacturers include: American Hashi, Japanese DKK, E+H, Hana, Yokogawa, Mettler ； Domestically produced Leici should also be available.
