Clamp meters

The clamp meter supports you in the exact recording of current strength and uses the magnetic field that surrounds the conductor for its indirect measurement of the magnetic field. It is therefore not necessary to disconnect the electric circuit to activate the measuring instrument directly on the cable, because the measurement is contactless.

The advantages of the clamp meters testo 770

• 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
