Testo | Clamp Meters

The clamp meter supports you in the exact recording of current intensity and uses the magnetic field that surrounds the conductor for its indirect measurement.

Therefore, it’s not necessary to disconnect the electric circuit to activate the measuring instrument directly on the cable, because the measurement is contactless.

Benefits of Testo clamp meters

Unique hook-on function separates and grabs wires, without using your hands
Addictional functions for the current start, leakage and measurement within μA range
Communication with Testo app Smart Probes via Bluetooth

Precise clamp multimeters for various applications

The pincer-like iron core allows targeted splitting of the busbars. This operating method enables you to measure the current even where you cannot switch off the system temporarily. Using a clamp multimeter makes it possible to record multiple measurement data. These elements allow flexible use and ensure clear data collection.

When using the clamp multimeter, two important points must be kept in mind:

Only one single conductor can be grasped and measured,
If the clamp encloses an entire cable which contains both conductor and return conductor, only the leakage current is measured.

Clamp meter for leakage current – for even more precision

The Testo clamp meter for the leakage current is an important measuring instrument for precision work in electronics. Compared to the classic clamp meter, these diagnostic tools are very sensitive, which means you can also measure extremely small currents.

These high-quality and precise leakage current probes have also addictional functions employed to test the starting current and to measure data in the μA range. You can use this digital clamp meter in the following areas:

continuity and resistance testing,
voltage measurement,
RMS current measurement.
