GENERAL
                                        
                                    The pure zinc (Special High Grade-99.99% pure) will have a potential to copper sulfate electrode reasonably 
                                    close to -1.1 volt in most soils. A pure zinc reference electrode can be used effectively to avoid the 
                                    contamination of the solution in a copper sulfate electrode with change in its half cell potential that 
                                    caused by backflow of hydrostatic pressure (Because Zinc reference electrode do not contain any porous plug 
                                    and solution container). Therefore, zinc reference electrode is commonly used inside internally protected 
                                    steel water boxes, tanks, pipes etc.
