Description of a PH Meter

Components

• A pH meter consists of a probe or electrode and an electronic meter which displays the pH measurement. The electrode is usually covered by glass.

Types

• There are several types of pH meters including portable pH meters, benchtop pH meters, in-line pH meters and pH pens.

Uses

• Portable pH meters and pH pens are for home use or for field testing. Bench top pH meters are used in labs and classrooms. They are more accurate than portable or pH pens. In-line pH meters include pH transmitters, controllers and analyzers. They are used in an industrial setting and have individualized functions.

Function

• PH transmitters take a pH measurement and send it to a recorder. A pH controller takes a pH reading and, based on parameters, controls processes via relays. A pH analyzer combines the function of transmitters and controllers.

Applications

• A pH meter checks water quality, milk quality, soil condition, industrial processes and is utilized in wine-making and beer-making.
