pH Glass Electrode

pH Glass Electrode (wired)

This is a general-purpose plastic bodied, single junction gel filled glass electrode, which is non-refillable. The electrode has approximately 87 cm of wire between the top of the electrode body and the BNC connector.

Note: This electrode is no longer available please see BNC-Cap electrode 2253

Suitable for use with both the Wireless pH Adaptor and the SmartQ pH Adaptor.

  • Sealed Silver / silver chloride gel filled electrode
  • Isopotential point pH 7
  • 56mV per pH, 0 +/- 30mV at pH 7.0
  • BNC connector

Warranty & Support

All our sensors are supplied with 5 years warranty and lifetime support, this pH Electrode has a 1 year limited warranty.

Extra Info

Supplied with a pH storage bottle containing storage solution.

Tip: Maintain the level of storage solution, the pH sensitive glass membrane must be kept wet. Store the electrode tip in a 1:1 solution of pH 4 buffer and 3.5 to 4 mol dm-3 KCl. Do not ever store in deionised or distilled water
