No, a barometer measures pressure.
A hygrometer is a weather instrument that measures moisture in the atmosphere. It quantifies the amount of water vapor present in the air to provide information about humidity levels.
A device called a current meter is commonly used to measure water velocity. Current meters can be mechanical or electronic, and they work by directly measuring the speed at which water flows past a specific point in a river, stream, or other water body.
An ammeter is the instrument that measures electric current in a circuit. It is connected in series to the circuit to measure the flow of current through it.
An ammeter is commonly used to detect electron flow in a circuit. The ammeter measures the amount of current (flow of electrons) passing through a specific point in the circuit.
