Applications
Oil & Gas
Traditional pH and ORP sensors with porous/open reference junctions that are used in processes containing aggressive and toxic chemicals often fail because of reference electrode poisoning. Chemicals from within the process diffuse through the built-in porous/open junction(s) necessary for this type of sensor to operate and poison the Ag/AgCl electrode within the reference half cell.
Poisoning of the reference electrode leads to severe measurement performance issues and premature demise of the sensor. Apart from the high expense that comes about from the frequent replacement of these failing sensors, there is also the cost of safely [and legally] handling and disposing of what can be highly contaminated sensors. Improper disposal of contaminated sensors can have a significant impact on the environment and expose companies to additional cost risk through litigation and penalty
Potable Water
REFEX Water Treatment pH Systems are designed to give reliable, continuous real time measurement of water quality in water treatment systems.
Designed to be operated as a side steam, each system is supplied complete with a purpose built flowcell assembly that houses the measurement electrodes. REFEX pH electrodes are provided. The robust reference sensor uses a highly stable, rapid response, non-porus polymeric interface instead of a traditional porous liquid junction as used by all conventional reference electrodes. The non-porous nature of the electrode interface prevents the loss of electrolyte into the flow stream, preventing the rapid degradation of the measurement and costly frequent replacement of “consumable” probes. REFEX electrodes typically last 5 times longer than conventional electrodes in water treatment applications. The electrode is also highly resistant to fouling and coatings, greatly reducing maintenance overhead and providing high measurement uptime when in service.
Powerplants
Challenging application for pH Sensors in low ionic waters. Refex non porous ionically conductive Polymeric reference interface barrier means there's no liquid to liquid contact and exchange between the UPW and the Reference KCl electrolyte.
There's no diffusion potential osmosis errors, no KCl electrolyte dilution wash out. Stable mV reference potential.

(Bio)Pharma
Biotechnology processes are carried out in a sterile and highly controlled environment to prevent contamination and loss of material. Loss can be very expensive, with some media costing astronomical amounts of money.
To prevent cross contamination between batches, pH probes are often discarded after only being used once. The porous nature of traditional probes makes them impossible to clean completely, hence the disposable approach. REFEX probes can solve this issue as they are intrinsically non-porous and totally cleanable. Furthermore, the reference junction material is resilient to sterilization, with tests proving that REFEX reference probes can be sterilized many, many times without loss of effectiveness or operation.

Waste Water
There are many regulatory requirements at both State and Federal level regarding the discharge of wastewater from industrial manufacturing facilities.
Any company that discharges any sort of effluent into sewer systems, lakes, streams or the ocean is required to neutralize this effluent before discharge. Non-compliance can result, at a minimum in financial penalties and may include other consequences such as remediation of damage caused. It is in the best interests of any company (and depending upon local rules, can be compulsory) to record discharged effluent characteristics such as pH at the point where it leaves their facility.
