pH / ORP

Put simply, pH probes measure the volume of hydrogen ions in a solution. Higher ion concentrations make the solution more acidic (low pH), while lower concentrations mean the solution will be more alkaline (high pH).

Oxidative-reduction potential (ORP) probes measure the oxidative or reductive potential of a liquid sample. The more oxidative the solution, the higher the mV value will be (>0mV).

Measuring ph/ORP allows for effective process and chemical-addition control. This process is commonly used on plant effluent, boiler feed water, and other chemical solutions.
