What is Grounding and why is it important to ground a pH or conductivity measurement?

Equipment grounding can be described as the connection of the earth ground to a non-current carrying conductive material.
The function of the grounding is to provide a backup pathway, which is an alternative route for the current to the ground in case there is a fault in the wiring system.
One of the most important reasons for grounding electrical currents is that it protects the equipment and those working with it from surges in electricity.
Additionally, to this, grounding facilitates current flow directly to earth preventing damage to the equipment and helps stabilize voltage levels ensuring a stable measurement.
