Electrode Selection
Electrode Material |
Corrosion Resisting Property |
Stainless Steel |
Used for measuring water, waste water, inorganic acid, organic acid or other corrosive medium. |
Hastelloy B |
Good corrosion resistance of different concentration of hydrochloric acid under boiling point, resist the corrosion of non-oxidizing acid, alkali, non-oxidizing salt solution, such as sulfuric acid, phosphoric acid, organic acid, etc.. |
Hastelloy C |
Resist the corrosion of oxidizing acid, such as nitric acid, mixed acid, the mixture of chromic acid and sulfuric acid, oxidizing salt like Fe+++, Cu++ or other oxidants such as hypochlorite solution above ordinary temperature and seawater. |
Tungsten Carbide |
Used for measuring non-corrosiveness or strong abrasive liquid. |
Titanium |
Used for measuring seawater, kinds of chloride, pypocholoride, oxidizing acid (including nitrosonitric acid) and organic acid-base.
Not suitable for measuring pure reducibility acid (e.g. vitriol, hydrochloric acid).
Note: if there is oxidizing agent in acid, corrosion resistance will be greatly decreased. |
Tantalum |
Have excellent corrosion resistance, as much as glass.
can be used for measuring every chemical medium including boiling hydrochloric acid and vitriol below 175 ℃ , but there is exception of hydrofluoric acid, fuming acid and alkali.???? |
Platinum |
For measuring kinds of acid, alkali and salt, except aqua regia. |
Monel |
A kind of Nickel-copper alloy, suitable for every alkaline liquid. |
