Here are some of the benefits of using EDT directION combination Ion Selective Electrodes for process measurements:

  • Rugged Solid State Sensors
  • No Filling solutions
  • No membrane replacements
  • Built in dry Reference electrode
  • Waterproof and submersible
  • Complete with 5 metre cable
  • Compatible with all mV meters and controllers
  • Stored dry for long lifetime
  • Low cost
  • Easy to install

The Potassium sensor is PVC  based with a solid state mount and does not degenerate during storage unlike conventional Potassium electrodes. The lack of internal solution means that submersion is also possible as the sensor does not flex under reasonable pressure.

Each EDT directION Process ISE has a 5 metre cable and a BNC connector (other connectors including Free wire ends available on request- please specify) allowing use on all types of pH/ION meters and controllers.

For Quick Ion analysis for under £500 use our ION Concentration Calculator.

The solid state sensors have a huge advantage over conventional ISEs in that there is no internal fill solution to degenerate the sensor this means that EDT direction combination ISEs have an unrivalled lifetime and a very low cost of ownership.

EDT are a UK based manufacturer and produce ISEs for many prominent companies in the water testing sector. As a result our ISEs are very competitively priced and come complete with technical support provided from our vast library of applications and our in house electrochemistry technicians.

Please Note: To prolong the lifetime of ISEs it is ideal to install them in a sampling line if possible. This will prolong the lifetime of the ISE. If permanently immersed frequent calibration is recommended for applications where precision is required. 

PVC Electrodes should not be exposed Fats,Organics or surfactants.

Process ISEs will not last as long as Laboratory ISEs due to the permanent submersion. Typical lifetime in clean applications is 5000 hours.  

Typical drift is 2mV per 8 hours.
