Oxidizing and reducing reagents are used to participate in chemical reactions known as a redox reaction.\u003c\/p\u003e\n\u003cp\u003eAn important part of the ORP probe is to have a sensor that is chemically inert; meaning it cannot be oxidized or reduced itself. It must also have the proper surface characteristics to promote rapid electron exchange, a property known as high exchange current density. Two noble metals have proven to work well for this purpose: pure platinum and pure gold. Both are commonly used in the construction of ORP probes.\u003c\/p\u003e\n\u003cp\u003eThe platinum sensor is often preferred because it is mechanically simpler to produce. Platinum can be welded to glass and also has a similiar thermal expansion coefficient. Sensors made of gold cannot be welded to the glass and are often placed in plastic supports applied to the glass or plastic tube by means of tiny elastomeric bungs.\u003c\/p\u003e\n\u003cp\u003eMany industries rely upon ORP measurements including swimming pools, food processing, boilers and cooling towers, and plating. The measurement of ORP helps the user monitor the effectiveness of disinfecting compounds including chlorine and ozone. ORP is also used to monitor redox reactions including the use of bisulfite in the reduction of hexavalent chromium to trivalent chromium in plating wastewater.\u003c\/p\u003e\n\u003ch4\u003eFeatures at-a-glance:\u003c\/h4\u003e\n\u003cp\u003eWaterproof\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIP67 rated\u003c\/li\u003e\n\u003cli\u003eProtects the internal electronics of the meter from an ingress of water in the event that the meter is dropped into a tank or a body of water.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eStability indicator\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eHI98120 features a stability indicator tag on the LCD that will disappear once the reading stabilizes.\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eReplaceable electrode\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAn electrode last approximately one to two years.
