pH Sensors

Industry’s most innovative and reliable pH sensing technology

Say goodbye to sensor drift*

  • The Nexus® series is a solid reference material. Poisoning or leaching of the reference electrolyte that occurs in standard sensor is eliminated.
  • Nexus® also eliminates the need for ongoing maintenance or cleaning requirement due to fouling or film build up removal which occurs with traditional pH sensors.
  • The solid Nexus® reference provides for faster response time to changing pH values since there is no requirement for a junction.

* Due to poisoning or build up
