The ORP meter, also known as Oxidation-Reduction Potential, is an instrument widely used in industry and experiments; ORP is a comprehensive indicator of the environmental conditions of the medium (including soil, natural water, culture media, etc.), has been used for a long time, it characterizes the relative degree of oxidation or reduction of the medium. The unit of ORP is mv. ORP value (oxidation-reduction potential) is an important indicator of water quality. Although it cannot independently reflect the quality of water, it can combine other water quality indicators to reflect the ecological environment in the aquarium system.

What is PH/ORP?

PH: refers to the ratio of the total number of hydrogen ions in the solution to the total amount of matter. Generally called "pH" rather than "pH value". A numerical value that represents the pH of a solution, pH=-lg[H+], which is the negative value of the common logarithm of the hydrogen ion concentration contained.

ORP: Oxidation-reduction potential, referred to as ORP or EH. ORP has been used for a long time as a comprehensive indicator of the environmental conditions of the medium (including soil, natural water, culture medium, etc.). It represents the relative degree of oxidation or reduction of the medium.

What are pH meters/ORP meters used for?

As the name suggests, a PH meter/ORP meter is an instrument that detects the PH/ORP value in water samples. A PH meter is an important tool for measuring and reacting to the pH of a solution. pH value is one of the important physical and chemical parameters of aqueous solution. Any natural phenomenon involving aqueous solutions. Chemical changes and production processes are related to pH value. Therefore, pH value needs to be measured in the fields of industry, agriculture, medicine, environmental protection and scientific research. ORP value (oxidation-reduction potential) is an important indicator of water quality. Although it cannot independently reflect the quality of water, it can combine other water quality indicators to reflect the ecological environment in the aquarium system.

ORP scope of application

1. Industrial wastewater treatment

Redox potential is a measure of electron activity, much like how hydrogen ion activity is measured.

If sodium disulfide or sulfur dioxide is added to wastewater, hexavalent chromium ions can be converted into trivalent chromium ions. The redox system used in water treatment mainly involves the reduction of chromic acid and the oxidation of cyanide. The addition of chlorine or sodium hypochlorite can be used to oxidize cyanide, followed by hydrolysis of cyanogen chloride to form cyanate. This chemical reaction process is called a redox reaction system.

2. Disinfection and application of water

If the redox potential value of pool water and mineral water is equal to or higher than 650mv, it means that the bacterial content is acceptable. The redox electrode can measure the disinfection effect of swimming pool water, mineral water and tap water. Because the bactericidal effect of coliform bacteria in water is affected by the redox potential, the redox potential is a reliable indicator of water quality.

3. Changes in soil ORP

View dynamic changes in ORP in soil, etc.

4. Applications in other fields

Applied to environmental protection, ocean exploration, bioengineering, the brewing industry and other national economic sectors, etc.
