SenTix® pH electrodes for every application

SenTix® quality electrodes by WTW – convenient measurement and precision.

  • Low-resistance glass membranes guarantee stable measuring signals even at low temperatures.
  • Silver ion-free reference electrolyte, together with the proven platinum wire diaphragm, prevent measurement problems by precipitating silver compounds.
  • Functional slide for accessing the refill opening for electrodes with liquid electrolyte.
  • Typical connections: Waterproof DIN connector, BNC connector, fixed cable (1 or 3 m) or connector head (S7 or SMEK).

Low-maintenance pH electrodes with gel electrolyte

  • SenTix® 20
  • SenTix® 21
