A Buyer's Guide To Voltmeters


A voltmeter (also known as a voltage meter) is an instrument used to measure the voltage between two points in an electric circuit. They are different from ammeters - devices used to measure the electric current in a circuit.

Voltmeters can be found in industrial plants, workshops and in the marine, automotive and resources sectors and are commonly used to check power generators, batteries, electrical appliances, heavy-duty equipment and tools to maintain safe working conditions.

Today both analogue and digital voltmeters can be found on the market. Analogue voltmeters use a needle and calibrated scale to indicate values, but digital voltmeters display values on a digital screen. Digital voltmeters have been increasing in popularity in recent years due to their quick and easy readability.
