Product Description

Oxidation potential (or ORP) is the oxidation or reduction of material nature of the community.
Standard conditions, using accept or release electrons of metal electrode, the value can be determined. Metallic platinum or gold electrodes can be used (Pt or Au).
Electrode material must not react with the tested substances inert metal.
If the aqueous solution containing the oxidant or reducing agent, then the conduct of electronic exchange.
In the acid / base reaction is hydroge n ion H + exchange, while in other chemical reactions in the electronic exchange.
The process called reduction and oxidation, that is, oxidation and reduction reactions, oxidation-reduction time for purification to remove cyanide, chromate, nitrite is extremely important.
Those who can deliver one or more electronic material known as reducing agent and the electron is the oxidant. Therefore, reduction in the number of electrons increase in the number of electrons in the oxidation reduction reaction.
Our products are introducing advanced technology and imported components, greatly reducing the volume, reduce costs and maintain their good quality, so that the use of ORP has been popular.
