What is pH and ORP?

pH Controllers

A pH controller is an automated device that monitors and adjusts the acidity or alkalinity of a solution. It measures the concentration of hydrogen ions, giving a numerical value that informs users whether the solution is acidic (pH below 7) or alkaline (pH above 7). These controllers can automatically dispense acids or bases to reach target pH levels.

ORP Controllers

ORP, or oxidation-reduction potential, measures the electron activity in a solution. ORP controllers help maintain the right level of disinfection in water, ensuring that the water stays safe for various applications. A higher ORP indicates a strong ability of the solution to oxidize contaminants, while a lower ORP shows reduced ability.

Key Applications of pH and ORP Controllers

The utilization of pH and ORP controllers spans multiple sectors due to their critical role in process optimization.
