Clever Digital Multimeters

Testo’s digital multimeters manage without a dial, and avoid 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
  • True root mean square measurement (TRMS)

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

Innovative Clamp Meters

Do you have the ideal clamp meter for non-contact measurement of both current and voltage, as well as other electrical parameters in tight switching cabinets? We do.
 
  • Innovative clamp mechanism for easily grabbing individual cables
  • With additional functions for starting current, output, and measurement in the μA range
  • Communication with the testo Smart Probes app via Bluetooth
