Go Direct® pH BNC Electrode

A general-purpose pH electrode that connects to a Go Direct® Electrode Amplifier.


The Go Direct pH BNC Electrode is a gel-filled combination pH electrode designed to make measurements in the pH range of 0 to 14. A polycarbonate body that extends below the glass sensing bulb of the electrode makes this probe ideal for the demands of a middle school, high school, or university level science class or for making measurements in the environment. The gel-filled reference half cell is sealed—it never needs to be refilled.


  • Type: Sealed, gel-filled polycarbonate body, Ag/AgCl
  • Response Time: 90% of final reading in 1 second
  • Temperature Range: 5 to 80°C (readings not compensated)
  • 12 mm outer diameter
  • Range: pH 0–14
  • Isopotential pH: pH 7 (point at which temperature has no effect on output)
  • BNC Connector
