Panel meters are electronic measuring instruments designed to display electrical or physical measurements in an easy-to-read format. They are typically installed in control panels, equipment enclosures, and industrial systems to monitor parameters such as voltage, current, temperature, pressure, frequency, and power.

Panel meters may use digital displays, analog indicators, or programmable interfaces, with some models offering alarms, data logging, communication interfaces, and remote monitoring capabilities.
