These Sofamel electronic voltage detectors have a microcontroller and direct contact detection. They ensure the working environment is safe by detecting voltage by direct contact to indicate an electric field. The instruments are equipped with an automatic shutdown to standby mode after two minutes in the absence of voltage. In this mode, the consumption is less than 1 μA, and it stops working when the battery is low.
Ten models are available to choose from each with their own rated voltage, ranging from 1 to 3.3 kV to 22 to 79 kV.
