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.

Liner material

Main performances

Applicability

Polytetrafluoroethylene
(PTFE)

Chemical properties, resist the corrosion of
Boiling Hydrochloric acid, sulfuric acid, nitric
acid, aqua regia,Concentrated alkali and many
kinds of organic solvent, unable to resist the
corrosion of chlorine trifluoride, high
Temperature vanadyltrifluoride, high flow-rate
Liquid fluorine, liquid oxygen and ozon;

2.Poor abrasion resistance;

3.Poor ability of anti-negative pressure.

1.100℃，150℃(special order
required);
2.Strong corrosive medium like concentrated acid , alkali, etc.;
3.Sanitary medium.

polychloropree rubber
(Neoprene)

1. Excellent elasticity, high degree of tensile

strength,good wear resistance;

1. Able to resist the corrosion of generally low

concentration acid, alkali and salt, unable to
resist that of the oxidative medium.

1.80℃,120℃(special order
required);
2.General water, polluted water, weak wear ability mud and ore pulp.

Polyurethane rubber
(PU)

1. Excellent wear resistance (ten times of the natural rubber’s);

2.Poor abrasion resistance of acid and alkali;
3.Not able to work with water mixed with organic solvent.

1.＜80℃;
2.Middle and strong wear ability ore pulp, coal pulp, mud, etc..

PFA

Having the same abrasion resistance with
PTFE.Having strong ability of load pressure
resistance.

1.Below 220 deg C
2.Applicable in state of load pressure.

F46

1.Have the same abrasion resistance with PTFE.

2.Resistable for low abrasion.

3.Having strong resistance to load pressure.

1.Below 220 deg C
2.The same as PTFE.
3.Applicable in mediums of low abrasion.
