An Oxidation Reduction Potential (ORP) Sensor measures the activity of oxidizers and reducers (redox) in an aqueous solution.
Delta-Phase incorporates easily replaceable cartridge electrodes into the RX7 Field Rebuildable sensors that widely covers ORP measurements including most municipal water and wastewater, recreational water and industrial process water and wastewater applications.
The RX7 sensors are ideal for both handheld and in situ applications and offer quick time response, minimal flow dependence and low power consumption.
The cartridge electrode features a “long life” reference element eliminating the need to frequently replace the electrode cartridge.
The best use of an ORP measurement is in monitoring and controlling oxidation-reduction reactions, such as Chlorination and Dechlorination.
RX7 sensors come with different mounting configurations including immersion, flow-cell and insertion /retractive ball-valve assembly installations.
APPLICATIONS
Waste water treatment
Monitors the oxidizing or reducing power in effluent to Biological Tanks to avoid killing useful bacteria.
Recreational Water
Swimming pools, Waterparks, Spas, etc.
Typical Industrial process control
■ Cooling Tower chlorination/dechlorination
■ Cyanide destruction
■ Chromate reduction
■ Hypochlorite bleach production
