pH Meters Manufacturers

pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid. A typical pH meter consists of a special measuring probe (a glass electrode) connected to an electronic meter that measures and displays the pH reading. They range from simple and inexpensive pen-like devices to complex. They also have expensive laboratory instruments with computer interfaces and several inputs for indicator (ion-sensitive, redox), reference electrodes and temperature sensors such as thermoresistors or thermocouples. This has a probe, which measures the concentration of hydrogen ions surrounding a thin-walled glass bulb at its tip. This probe produces a small voltage that is measured and displayed as pH units by a meter.
