Definition
ORP (Oxidation-Reduction Potential) is a measurement (in millivolts, mV) of how strongly a solution can either gain or lose electrons in chemical reactions.
Positive ORP values indicate an oxidizing environment (more likely to kill bacteria or break down organics)
Negative ORP values indicate a reducing environment (more likely to support microbial activity)

How It Works
The sensor has a measuring electrode (usually platinum) and a reference electrode.
It detects voltage differences caused by electron transfer between oxidizing and reducing agents in the water.
This voltage (ORP value) gives insight into the water's chemical properties.
