Clever digital multimeters
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
Innovative clamp meters
Don’t 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 Probes App via Bluetooth
Voltage testers which also measure current
The first voltage testers in line with DIN-EN 61243-3:2010 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
Voltage testers with 360° display
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
Non-contact voltage testers
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
