AQUA-NOA pH gel electrode with BNC connector

  • Quality electrode for all common pH controllers and pH meters with BNC connector
  • gel electrode
  • Protective cap filled with storage solution
  • 1.5 m cable length
  • Measuring range: pH 0.00 - 14.00
  • Temperature: 0 - 50 °C

This pH electrode or combination electrode, as it is correctly called in technical jargon, is well suited both for continuous measurement on the pH controller and for individual measurement on the pH meter for a range of aquariums.

Necessary care and accessory items such as cleaning and calibration solutions can also be found here. We have linked these items for you in the »Accessories« tab.
