PH meter

From Academic Kids

The title of this article is incorrect because of technical limitations. The correct title is pH meter.

A pH meter is a specific type of voltmeter with a very high impedance of the input channels. The high impedance is a necessary part of the equipment because of high resistance of the pH glass electrode typically used with pH meters. The common pH meter has several inputs: for indicator (ion-sensitive or redox) and reference electrodes and temperature sensors such as thermoresistors or thermocouples.

The pH scale of the device should be calibrated by several buffer solutions. This correlates the measured potential of the indicator electrode with the pH scale.nl:pH-meter ru:PH-метр
