Measure Ozone in water with ORP Meters

How does an ORP Meter work?

ORP stands for oxidation-reduction potential. It is a measure of the ability of a solution to oxidize or reduce other substances.  ORP may also be referred to as redox Potential. 

ORP levels in water can be measured with an electronic  ORP meter.  ORP meters use electrodes in water that measure the voltage difference between the two electrodes.  Water with a higher potential to lose electrons (oxidize) will create a higher ORP reading, measured in Millivolts (mv).  Lower, (potentially negative) ORP values indicate the water is more reducing.

Using ORP to Measure Dissolved Ozone

ORP meters can indicate dissolved ozone levels in water. Ozone, being a strong oxidizer, increases water's ORP. However, other factors like pH, dissolved oxygen, and other substances can also affect ORP, meaning there's no direct correlation between ORP values and ozone levels.

For specific applications, ORP meters can be calibrated or correlated to known ozone levels, provided other water parameters remain stable. This makes ORP valuable for monitoring changes in dissolved ozone and general water quality.

These tools can be used to measure ozone in water for correlation purposes:
