Camlab EpoxyTough Flat End pH Electrode
Camlab EpoxyTough pH electrodes are tough epoxy bodied combination with a gel filling so you never need to worry about electrode maintenance or refilling again. They are compatible with nearly every pH meter straight out of the box or with a simple adapter cable. Standard models feature an extended body which protects the sensitive pH sensing bulb. You can even use an EpoxyTough to stir your sample with to get a fast stable reading.
Available in single or double junction designs, spear tip, flat surface, micro and extended body versions, there is a Camlab EpoxyTough electrode to suit your requirements.
The ExpoyTough flat double junction combination electrode provides added protection for contamination of the reference, providing a longer life. This robust and easy to clean electrode is ideal for measuring hard to clean fluids and for low volume pH measurement.
The probe will need proper maintenance and cleaning with the correct cleaning solutions. Camlab can also supply cleaning solutions to remove proteins, sulphides and organic components from the probe to ensure optimal performance.
