Purpose
The instrument is used to test the degree of steel-bar corrosion in electrochemical method.
Specification
GB50204-2002
Performance
1. Two test mode. The potentiometry and gradient method is used to test steel-bar corrosion which fit for different working field.
2. Permanent reference electrode. Saturated CuSO4 solution is sealed up completely in reference electrode. Field test keeps clean, simple and pollution-free operations.
3. Automatic measure environmental temperature. Instrument design to contain a measure environmental temperature module, it can measure, record and display environmental temperature quickly no thermometers required.
4. Can save test date. Convenient for laborer data management.
5. Display test result intuitively. Display test result used icon mode, The icon color is more dark, the steel-bar corrosion is more serious. User can observe the corrosion degree intuitively.
6. Real USB transmission. Data can be transmitted to computer for future process and analysis.
7. Powerful data process and analysis software in windows. Software can display analysis result by spectrum and isoline. Test data can be export to word or excel easily.

It is widely used as a multi-functional petroleum additive, with resistance to abrasion, corrosion, oxidation and rust. it also has a protective effect on stainless steel, Iron, and nickel alloy.
HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better. HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.

The aqueous solution of hydrogen fluoride gas is a clear, colorless, fuming corrosive liquid with a strong pungent odor, easily soluble in water and ethanol, and slightly soluble in ether. Hydrofluoric acid is a weak acid with strong corrosiveness, which can strongly corrode metal, glass and silicon-containing objects. It is generally produced in laboratories with fluorite (mainly composed of calcium fluoride) and concentrated sulfuric acid. It needs sealed in a plastic bottle. The chemical industry is used to produce organic and inorganic fluorides (such as potassium fluoride, magnesium fluoride, uranium hexafluoride, calcium fluoride helium, fluororesin, fluoroplastic, fluororubber), dye synthesis, organic synthesis catalyst, and flame-retardant agent etc. In glass processing and production, it is used for frosted bulbs and general bulb treatment, glassware polishing, glass instrument scales, glassware and mirror engraving and lettering. As a cleaning agent for pickling of metal surfaces such as stainless steel. Used in the atomic energy industry, for the production of elemental fluorine and fluorides, and also as catalysts and fluorinating agents.
