Gel Plastic ORP Electrode

Related to the overall availability of electrons in the media, specifically the ratio of positive and negative ions in the solution. Also called Redox electrode. ORP is the only practical method for electronically monitoring sanitizer effectiveness. ORP value is an important parameter of water and is a measurement to oxidize contaminants. Normal application areas are swimming pools, fish farming, and aquariums. ORP is expressed in millivolts (mV). A range of -1000mV to 1000mV is common with most ORP tests. The pH value influences the ORP value significantly. If the platinum band or disk is contaminated, the electrode should be cleaned, otherwise response time will slow or inaccurate measurements will be given.
