	pH and ORP probes are both used for measuring the acidic intensity of liquid solutions. A pH probe measures acidity on a scale from 0 to 14, with 0 being the most acidic and 14 being the most basic. Similarly, an Oxidation-Reduction Potential '''(ORP)''' probe returns a voltage proportional to the tendency of the solution to gain or lose electrons from other substances (which is linked directly to the pH of a substance).		pH and ORP probes are both used for measuring the acidic intensity of liquid solutions.

	Since glass pH electrodes measure H+ concentration relative to their reference half-cells, they must be calibrated periodically to ensure accurate, repeatable measurements. Although calibration against one pH reference buffer (one-point calibration) typically ensures accurate pH measurement, frequent two-point or even three-point calibrations ensure the most reliable results. Make sure your pH system includes calibration buffers for a range of pH values.

	The two types of probes are pH and ORP. They are constructed in more or less the same way, the only difference being the chemical they contain to form the battery with. The different chemical means they measure a different value. The only decision to make when choosing between a pH probe and an ORP probe is what scale you want the output to be in.
