About pHpH stands for “potential hydrogen”. It measures alkalinity or acidity on the pH scale that runs from pH0 to pH14. A pH7 is neutral which means it is neither alkaline nor acidic. Values below pH7 neutral are said to be acidic and values above pH7 are alkaline. The scale is logarithmic (like the Richter Scale), meaning each full point increases or decreases by a factor of x10 rather than a single unit. For example a pH8 is ten timesmore alkaline than pH7, and a pH9 would be 10×10, or one hundred timesmore alkaline than neutral. Typical tap water in the US or Canada runs at between pH6.0 and pH7.25 although extremes exist.neutral pH = 7,0 / acidic pH < 7,0 / alkaline pH > 7,0 [/ig_text]
ORP = Oxydation Reduction Potential.The other way an ionizer alters the water is to turn it into a powerful antioxidant, measured as ORP (“Oxidation Reduction Potential”)– It is a more complex concept and is an extremely difficult measure accurately. ORP is sometimes referred to as “Redox”. An ionizer’s alteration of the ORP of your drinking water is what causes the microclustering, antioxidant and hydrating effects. ORP is a “potential” energy that is stored and ready to be put to work. An analogous way to look at ORP would be to consider pressure. When you blow up a balloon you use energy that creates force. As long as the balloon remains closed, this force is a “stored potential energy” in this case measured as air pressure. When released, this “potential” energy becomes kinetic energy. Potential electrical energy in liquid can be measured. It is measured with an ORP meter. These meters display extremely slight, and highly variable differences in the electrical properties of water. ORP readings are expressed in millivolts (1/1000 of a single volt). ORP meters range in price from $100 for a handheld “tester” to over $3,000 for more sophisticated laboratory equipment. Regular cleaning and calibrating with proper solutions is even more crucial than with pH meters to achieve accurate and consistent readings. ORP measures the presence of oxidizing or [oxidation] reducing agents by their specific electrical charge, thus Oxidation Reduction “Potential”. Oxidation in simple terms is what turns an apple brown after it is cut or causes metal to rust. Rust weakens metal and signifies the deterioration of the apple. High pH water has more “reducing” agents (-ORP) and low pH water has more oxidizing agents ( ORP).The ORP of most tap water in the USA is between 150 to 600mv and so is an oxidizing agent. High pH ionized water demonstrates a –ORP and so is a reducing agent or “antioxidant”.
