What is pH meter used for?
pH meter is an instrument used to measure acidity or alkalinity of a solution — also know as pH. pH is the unit of measure that describes the degree of acidity or alkalinity. It is measured on a scale of 0 to 14.
The quantitative information provided by the pH value expresses the degree of the activity of an acid or base in terms of hydrogen ion activity. The pH value of a substance is directly related to the ratio of the hydrogen ion [H+] and the hydroxyl ion [OH-] concentrations. If the H+ concentration is greater than OH-, the material is acidic; i.e., the pH value is less than 7. If the OH- concentration is greater than H+, the material is basic, with a pH value greater than 7. If equal amounts of H+ and OH- ions are present, the material is neutral, with a pH of 7. Acids and bases have free hydrogen and hydroxyl ions, respectively. The relationship between hydrogen ions and hydroxyl ions in a given solution is constant for a given set of conditions, either one can be determined by knowing the other.

Frequently Asked Questions
Effects of Temperature on pH
Temperatures Above 25°C: temperature compensation lowers high pH and raises low pH, resulting in value closer to neutral. Temperatures Below 25°C: temperature compensation raises high pH (more basic) and lowers low pH (more acidic), resulting in values further away from neutral. Whether or not temperature compensation needs be used is a matter of the needed pH accuracy. For example, if the accuracy requirement is ±0.1 pH, at a pH of 6 and a temperature of 45°C (113°F), the error is 0.06, well within the accuracy requirements. On the other hand, with the same ±0.1 pH accuracy requirement, operating at pH 10 and 55°C (131°F) would give an error of 0.27 pH and compensation should be used.
When compensation is required, it can be done in one of two ways. If the temperature fluctuates, then an automatic compensator should be used. If the temperature is constant within several degrees C, then a manual compensator can be used. If no compensator is needed, a fixed resistor can be installed across the temperature compensator terminals. Any of the above devices–automatic compensation, manual compensation or fixed resistor–operate as a function of the pH meter’s electronic circuit. As such, information and parts should be obtained from the meter manufacturer. If automatic compensators are used, they should always be at the same location as the pH electrode. When electrodes are calibrated in buffer, the temperature compensator also should be in the buffer. In a similar way, a manual temperature compensator should be adjusted to reflect the temperature to which the pH electrode is exposed during both calibration and operation.
