	Teledyne offers two proven standard sensor configurations as functioning receptacles for its Oxidation Reduction Potential (ORP) cartridge. The SP-1 immersion or the SP-2 valve retractable sensors come in a variety of materials to further enhance the resistance of aggressive corrosion aqueous media and can be ordered in varying lengths to meet installation requirements.

Features Teledyne’s ORP electrode and sensor have a low physical profile (3/4” dia) that allows for greater ease of insertion into potentially high flow rate/pressure pipelines. Selectable sensor housing lengths allow for reaching deep aeration basins or vats. The ORP electrode (cartridge) is replaceable (as a component of the sensor) at a much lower life cycle cost than that of the competition. The sensor has a preamp (signal conditioner) integral to the sensor that provides a cleaner signal for transmission over longer cable lengths. Attempting to measure ORP with a pH electrode will yield an unacceptable offset in mV. An oxidizing agent such as quinhydrone (cyclohexadiene) must be added to the buffer to develop a measurement standard. Being acidic, the quinhydrone must be used @ 7pH or less (4pH). This, then, will approximate a correct mV reading of 59.1 per decade.
