In the world that surrounds us, we do not see it, but there is a continuous exchange of electrons that takes place between substances in the air, in the earth, in water, and in our bodies.  This phenomenon is known as ion exchange.

In an effort to reach a state of stability, substances that are lacking electrons are desperately seeking out electrons wherever they can: these substances are referred to as oxidizing agents.  On the contrary, substances which have a surplus of electrons are capable of donating their extra electrons: these substances are referred to as reducing agents, or anti-oxidizing agents.

Oxidation-reduction potential, or ORP, is a measurement that indicates the degree to which a substance is capable of oxidizing or reducing another substance.   ORP is measured in millivolts (mV) using an ORP meter. 

  • A positive ORP reading indicates that a substance is an oxidizing agent.  The higher the reading, the more oxidizing it is.  
  • A negative ORP reading indicates that a substance is a reducing agent.  The lower the reading, the more anti-oxidizing it is.  

Most types of water, including tap water and bottled water, are oxidizing agents as their ORP value is positive. 

Alkaline ionized water is an anti-oxidizing agent, as it has a negative ORP value and it is able to donate extra electrons to neutralize the harmful effects of free radicals on the body.  Most other types of water are oxidizing agents as their ORP is positive.

How it works:

1. Remove the protective cover. 
2. Touch the "ON / OFF" switch, power. 
3. Place the electrode in the test solution and gently shake until after the show read the display value is stable. 
4. Touch the "HOLD" key, then keep the value of the current measurement. If you need to re-measure, then press the "HOLD" button is automatically released on hold. 
5. After use, press the off switch, the electrode with distilled water, put on protective sleeve.
