• Electrodes for pH-Measurement
  • Length: 120 mm
  • Shaft material: Glass or Epoxy
  • Diameter: 12 mm



The electrode always has to be calibrated together with the controller. The calibration frequency depends on the temperature, the application and the maintenance. Buffer solutions are available on demand.
