Testo’s digital multimeters manage without a dial and avoid any incorrect settings! It doesn’t matter whether you are measuring a voltage or an ionization current – there couldn’t be more reliability.

• Automatic detection and selection of measurement parameters via socket assignment

• Easy operation via function keys and large illuminated display

• With true root mean square measurement TRMS

Do you have the ideal clamp meter for non-contact measurement of both current as well as voltage and other electrical parameters in tight switching cabinets? We do.

• Innovative clamp mechanism to grab individual cables without any problem

• With additional functions for starting current, output and measurement in the μA range

• Communication with the testo Smart App via Bluetooth

The first voltage testers in line with DIN-EN 61243-3:2014 which also measure current. Ideally suited for almost all measuring tasks involved in testing current and voltage.

• Reliable voltage display, even with an empty battery

• Measure immediately without any switching on or selection

• Exchangeable measuring tips

Only Testo has voltage testers with all-round display. Thanks to unique light technology, readings can be clearly seen from any position. This means you can measure voltage more reliably.

• Certified according to the DIN-EN 61243-3:2010 voltage tester standard

• Anti-slip ring for a secure hold when testing

• Safety specification according to CAT III

The non-contact voltage tester is particularly suitable for initial checking of a possible fault source. Indispensable for work on electrical systems!

• Voltage range up to 1,000 V

• Filter for high-frequency interference signals

• Adjustable for phase detection or voltage indication
