pH meter measure the acidity or alkalinity of a substance. They are commonly used for water testing, and for biological sample analysis in hydroponics, aquaculture and agriculture. A portable meter is commonly used to measure the pH of substance such as food, beer, or wine, and is also used to test cleaning water, rinse water, and wastewater, in lab, industrial and food applications.

pH and ORP Electrodes.
pH is the Unit of Measure used to express the degree of acidity of a substance and ideal for use in Aquariums and elsewhere.
pH electrodes and ORP electrodes are analytical sensors for measuring pH and oxidation-reduction potential (ORP). These electrodes can be for measuring either pH or ORP, or both. pH is the negative logarithm of the hydrogen ion activity in solution. The pH value of a substance is directly related to the ratio of the hydrogen ion [H+] and the hydroxyl ion [OH-] concentrations. It is one of the most common laboratory measurements because many chemical processes are dependent on pH. Oxidation-reduction is a type of chemical reaction in which electrons are transferred from one substance to another. The oxidized species loses electrons and the reduced species gains electrons. Both species must be present for the reaction to occur.
Important specifications for pH electrodes and ORP electrodes are measuring ranges and accuracies, as well as response time, which is typically given as time to reach 95% of final value. pH electrodes and ORP electrodes are available as either single cells or combination cells. Single cells, one part of an electrode pair, require separate reference electrode and are the best choice for colloidal suspensions, iodides in sample, and high percentage of solids in fluid. Combination electrodes are composed of two parts, the measuring electrode and the reference electrode. This is the most common configuration and is best for laboratory or field applications.
Reference electrodes can be either refillable or sealed. The trade-off between the two is amount of maintenance versus length of product life. Refillable electrodes obviously need more maintenance, but also last longer and typically have higher accuracies. Sealed electrodes, while not requiring refilling, have a limited life, as the chemicals inside get used up and not replaceable.
