Digital ammeters are instruments that measure current flow in amperes and display current levels on a digital display.

Analog multimeters are instruments that are used to measure electrical quantities such as voltage, current, resistance, frequency and signal power

Digital multimeters (or multi-meters) are used to measure electrical quantities such as voltage, current, resistance, frequency, temperature, capacitance, and time period measurements

Analog panel meters measure and display processes and electrical variables with a simple dial display

Analog ammeters are metered instruments that measure current flow in amperes.

Clamp meters are ammeters that can measure current without the need to disconnect the wires where the measurement occurs.

Digital voltmeters are instruments that measure voltage or voltage drop in a circuit.
