1. Removable electrode cable connection.
2. Internal Ag/AgCl reference chamber fill port.
3. Electrolyte bridge fill port.
4. Internal annular ceramic reference junction.
5. Annular ceramic primary reference junction.
6. pH bulb or platinum band sensor.
7. 12mm O.D. shaft. 
The immersion length A is determined by the immersion depth H of the probe plus 70mm.


Oxidation Reduction Potential (ORP) is, simply put, an indication of a solution's ability to oxidize or reduce another solution. It is a ratio of oxidized species to reduced species in a solution containing both. Some commonly used oxidizers include chlorine, ozone, bromine, sodium hypochlorite, and hydrogen peroxide. Examples of reductants include sodium bisulfite (also known as sodium metabisulfite) and sulfur dioxide. The terms "ORP" and "Redox" are both commonly used and are interchangeable.
