Electrodes



Sonic Supply’s range of high-quality electrode sensors are manufactured by two trusted laboratory instrument specialists: Sentek and Bante. Here you will find both conductivity and pH sensors for use in laboratory and educational environments. All of our electrode sensors are hand blown by highly skilled glass blowers, guaranteeing the highest quality in pH and conductivity electrodes.

Conductivity electrodes are simply used as a tool to measure the electrical conductivity of a solution. A pH electrode works in the same way, but instead takes this voltage value and then converts it into a pH reading. Both of these tools must be used alongside a pH or conductivity meter in order to calculate the desired measurement.

For any assistance in choosing your electrode, please contact us either by telephone (844)977-6642 or email sales@sonicsupply.com.
