ORP IN WATER
Similar to classifying solutions as acidic or alkaline by measuring pH, solutions can also be classified as oxidizing or reducing based on ORP measurements. This type of calibration is called relative mV calibration. An ORP sensor must be chemically inert; it cannot be oxidized or reduced itself. It must also have suitable surface properties to promote rapid electron exchange, a property known as high exchange current density. Two noble metals are used for this purpose: pure platinum and pure gold are both used in the construction of ORP sensors. Platinum sensors are often preferred because they are simpler and safer to manufacture. Platinum can be welded to glass and has the same temperature coefficient. Gold sensors cannot be welded to glass and are usually applied in glass or plastic tubes by means of small elastic bungs. Many industries require ORP measurement such as swimming pools, food processing, boiler and cooling towers, and plating. ORP measurement helps monitor the effectiveness of disinfectants including chlorine and ozone. ORP is also used to monitor redox reactions including the use of bisulfites in the reduction of hexavalent to trivalent chromium in electroplating wastewater.
POCKET-FORMABLE, COMPACT DESIGN
With convenient pocket clip and compact design, you can take it anywhere.
