Ever wonder how pH sensors actually work? This video goes through the basic design and functionality of the standard glass membrane combination pH sensor.

Topics within the video:

  • What is pH actually measuring?
  • The relationship with hydrogen ion concentration and millivolt output of the sensor
  • Measurement electrode versus reference electrode
  • Zero point (offset) and slope values
  • What are the effects of temperature on pH measurement?

Hamilton also publishes a comprehensive measurement guide to pH measurement. Topics covered included sensor design, calibration, storage, and care.
