Online ORP Analyzer
Water ORP (Oxidation-Reduction Potential) Controller is a critical tool for determining the oxidative or reductive capability of water. This crucial metric represents the water's ability to neutralize pollutants and provide effective disinfection, making it essential for maintaining excellent water quality in a variety of applications. ORP controller takes real-time millivolt (mV) readings, providing significant information about water disinfection performance and chemical stability by assessing the balance of oxidizing and reducing agents.

Oxidation-Reduction Potential (ORP) is defined as the difference between the redox potential of the indicator electrode and that of the reference electrode in a solution. It serves as a comprehensive metric reflecting the overall redox state of the system. ORP quantifies the macroscopic redox characteristics of all substances within the solution, specifically indicating the tendency for electron transfer. A positive ORP value signifies the oxidizing nature of the solution, whereas a negative ORP value denotes its reducing properties.
-pH Value
An increase in pH value typically results in a decrease in Oxidation-Reduction Potential (ORP), as oxidants tend to be more active in acidic environments.
-Dissolved Oxygen (DO)
The concentration of dissolved oxygen (DO) is positively correlated with ORP and serves as a critical indicator of aerobic conditions. For instance, when DO levels in an aerobic tank exceed 2 mg/L, ORP values are relatively high. Conversely, under hypoxic conditions where DO is less than 0.5 mg/L, ORP decreases significantly.
-Organic Substances and Reducing Agents
High concentrations of organic substances, such as chemical oxygen demand (COD), consume oxidants and thereby reduce ORP values. Reducing agents, including hydrogen sulfide and ammonia, directly weaken the oxidizing capacity, leading to a reduction in ORP.
-Ion Interference
Heavy metal ions, such as iron (Fe²⁺), manganese, and copper, can alter ORP through redox reactions (e.g., Fe²⁺ oxidation reduces ORP). Cyanuric acid, a by-product of swimming pool disinfection, inhibits chlorine activity, resulting in lower ORP readings. Phosphate indirectly promotes algae growth, which can lead to a reduction in ORP values.
