Sentinel Analysers

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.

• 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 oxidising agent such as quinhydrone (cyclohexadiene) must be added to the buffer to develop a measurement standard
• Being acidic, the quinhydrone must be used at 7pH or less (4pH). This will approximate a correct mV reading of 59.1 per decade
