Is the acid concentration meter the same as the pH meter?
Although only one word, absolutely not the same, the acid concentration meter is relatively high concentration (expressed as percent concentration of acid, for example) 5% sulfuric acid or 10% hydrochloric acid. This high concentration of acid (or alkali, salt) is not to measure the concentration of the common electrode, to be measured continuous automatic, with special electromagnetic concentration meter. Electromagnetic concentration meter of the earliest patent inventor (the first year of the implementation of the patent law in 1985 Chinese) and is currently the most widely used acid, alkali, salt concentration in Dalian Kolida Instrument Research Institute.
Acidity is also called pH, learned to know the chemical value of pH is the hydrogen ion concentration of negative value, it is not a substitute for acid concentration meter, a drop of concentrated sulfuric acid containing a hydrogen ion! PH glass electrode in sulfuric acid or concentrated alkali quickly damaged, do not measuring concentration of acid or alkali!
