ENV-50-pH Industrial pH Probe Operating principle A pH (potential of Hydrogen) probe measures the hydrogen ion activity in a liquid. At the tip of a pH probe is a glass membrane. This glass membrane permits hydrogen ions from the liquid being measured to defuse into the outer layer of the glass, while larger ions remain in the solution. The difference in the concentration of hydrogen ions (outside the probe vs. inside the probe) creates a VERY small current. This current is proportional to the concentration of hydrogen ions in the liquid being measured. This Industrial pH Probe can be fully submerged in fresh water or salt water, up to the tinned leads indefinitely. ENV-50-pH Industrial pH Probe Specifications
