For a wide range of applications

pH measurement shows a wide range of applications, from routine measurement in aqueous solutions up to special applications in a variety of media such as strong acid or alkaline solutions, with suspended solids or non-aqueous phases. The sample consistency can vary from liquid to firm, and measurements can be taken in a sheltered laboratory environment or outdoors in harsh conditions. Across all these variables, the range of SenTix® electrodes has the solution.

The SenTix range of electrodes include low-maintenance electrodes, precision electrodes, electrodes with or without temperature sensors, analogue electrodes and digital electrodes including IDS technology.

SenTix® pH electrodes analogue 

WTW SenTix® quality electrodes – measurement convenience and precision in one. 

  • Low-resistance membrane glasses warranty stable measurement signals even at low temperatures
  • Silver ion-free reference electrolyte together with the proven platinum wire junction prevents measurement problems due to precipitating silver compounds
  • Functional slider for opening and safe closing of the refill opening with electrodes with liquid electrolyte
  • Connection possibilities: waterproof DIN plug, BNC plug, fixed cable (1 or 3 m) or plug head (S7)

WTW's pH electrodes with IDS

  • Safe measurements by signal processing in the electrode
  • Easy exchange of electrodes thanks to calibration data stored in the sensor
  • Best GLP support due to automatic documentation of all relevant data
