Electrical Measuring Instruments

The non-contact voltage tester with a voltage range of up to 1,000 V AC is particularly well-suited to fast initial checking of any suspected fault sources.

The current-voltage tester for checking the voltage to the most current standards and simultaneously measure current. Therefore, they are suitable for almost all everyday electrical measurement tasks. The current-voltage tester automatically selects the correct settings and thus avoid dangerous maladjustments.

The clamp meter family, ideally suited for current measurement in switching cabinets. The testo 770-1 for daily measuring tasks, including starting current measurement, testo 770-2 with both μA area and a temperature measurement by means of an optional thermocouple adapter type K and testo 770-3 for calculating all output ratings, has a Bluetooth interface and the possibility of connecting to the testo Smart Probes App to show the measuring profile as a graph or to document it directly in a report.
