Here you will find voltage testers for measuring electrical magnitude in different fields of in electronics. All voltage testers have a large, clear display and fit in the palm of the hand, making them easy to handle. voltage testers are used, above all, in professional training, in education, the industrial sector and in workshops. They are invaluable to professionals due to their high level of accuracy. Here you will find all types of voltage testers for taking measurements of low to high voltages. We offer devices that have manual or automatic range selection and with or without an RS-232 interface for transferring data to a computer. The corresponding test cables of the voltmeter come with the device as well as batteries so that it is ready to use straight out of the box. voltage testers can be accompanied by an ISO calibration certificate either when it is ordered or included as part of an annual recalibration. This allows them to be integrated into the group of internal testing tools of a company.
