Voltmètres

Voltmeters present a convenient and easy-to-use tool for measuring the voltage. The meters can also be used to calculate the potential in direct-current or alternating-current circuits, and voltages developed in electrochemical or voltaic cells in chemistry applications. Models may offer audible or visual indication of voltage readings. The sensitivity ranges can be adjusted to sense particular voltage levels. All voltmeters are portable and are constructed from durable materials.
